An aftermarket exhaust system is at the top of most rider's mod list, but what can you really expect from that fancy pipe, and are stock exhausts all just junk anyway?
A lot of people think the stock pipe on their bike is just cobbled together as an afterthought. Twenty or thirty years ago that might have been the case, and, if you're riding a bottom-dollar bike that may still be the scenario, but for the vast majority of modern bikes, especially sportbikes and performance machines, the exhaust is very carefully engineered. In fact, after the engine, the exhaust system usually soaks up the most R&D resources. That's because it's key to the bike's performance, sound, appearance, and of course compliance with various emissions and noise regulations.
Don’t underestimate that stock exhaust, because every component has been carefully designed to fulfill a specific purpose, and there’s a lot more going on than meets the eye. Most manufacturers pour a ton of effort into designing a good system that provides strong power across the rev range, but stock exhausts are still heavily compromised due to the US and European noise and emissions regulations they must meet. And that is where aftermarket exhausts come in.
Aftermarket pipes are designed for closed course, competition use only. That means such exhaust are not street legal and therefore not restrained by all the rules that stock exhausts must follow. So while your bike’s stock pipe has to check a bunch of noise and emissions boxes, aftermarket exhausts’ only objectives are to cut weight, improve sound, add style, and boost power.
Surprised that I listed power last? It’s last because it isn’t the primary draw these days, or at least it shouldn’t be. Again, twenty years ago you could get big gains simply by slapping on a pipe, but these days, stock exhausts do a damn good job of offering broad, useful power. There is certainly still some room to improve performance, but if you install a full exhaust system, you absolutely have to do it in conjunction with a fuel controller like a Power Commander. If you’re not tuning your fuel to match your new system, you’re leaving power on the table and probably causing your bike to run lean. That means crappy throttle response, high engine temps, and lots of popping on decel.
In my opinion, the single biggest draw of an aftermarket pipe is weight savings. There’s a lot of crap on stock exhausts, and they’re huge! With no heavy catalytic convertor or massive sound-absorbing bread box or backpressure valve, race pipes can slash pounds off your bike.
There’s also a lot more style and attention to detail in the aftermarket, so swapping to a race pipe can turn your exhaust from an ugly necessity to a point of pride. Welds are more precise, there are nice touches like jacketed springs, polished pipe sections, and of course a trick muffler. Fancy finishes like carbon fiber and titanium are rarely available from the factory, but they’re pretty common on aftermarket systems and some companies really take it to another level.
Aftermarket pipes are louder, too, which some people like. I think race pipes sound obnoxious on the street, and they’re also illegal on account of that whole “competition use only” label. But if you’re still after a little more volume and better tone plus a dose of style, Yoshimura has a whole line of EPA- and CARB-compliant mufflers. And honestly, a slip-on muffler is going to be the best option out there for streetbikes. They’re cheaper, much easier to install, and in most cases won’t require an expensive fuel controller.
So, to summarize, your stock exhaust deserves respect for juggling a lot of difficult jobs, and aftermarket exhausts are good for reducing weight, improving sound and style, and possibly boosting power if you optimize your fueling to match it.

Admit it, most of us get an aftermarket exhaust coz of the sound
Marcus Loke and some solid weight savings
since when Buddha rides motorcycle?
Most definitely. Personally, I never pretended otherwise. I try convincing my friends that adding a full exhaust on a street bike is a waste (especially without a re-tune) but it usually falls on deaf ears. I think it's the bragging rights people like about it.
Sound, looks, weight and optimizing my machine in general. I doubt that I got a significant power increase from my Arrow exhaust system. But I do like the fact that my engine is not so plugged anymore. In combination with a nice K&N airfilter and a powercommander I feel like the whole thing can finally breathe more freely. That was also a main argument for me.
Marcus Loke Sound is an after thought with me. The aesthetics is why I get a slip on
_"Illegal because of noise and emissions compliance."_
[cue obnoxiously loud, street legal Harley drive-by]
Those Harleys usually have illegal exhaust as well
@@Blackflag.actual "illegal" meaning none
last week i saw some old bike, looked like it was from like the 50’s or 60’s, it drove by and after that huge bang, like it hurted my ears lmao
ps.. obnoxiously loud because of the sheer POWER... lemme guess.. your one of those rice racers who think that bike should need to wind up to 12000 rpm to develop any torque and sound like 50 swarms of angry wasps whilst doing it?
And half the street bikes and even cars and trucks these days.
“Look at me, look at me, pleeeese!”
I use aftermarket exhaust because it boosts my ego and Im racer wannabe..
So then you also have the Power rangers riding costume....Oh, I mean riding suit
@@toddlehman928 Correct, it has ego boosting technology
@@toddlehman928 Power rangers, unite!
So you can't afford one in other words, In fact you don't even have a bike but wish you did. And if you did have a bike you don't know how to ride it either.
@Stephen Penniket
Get a decent brain
If you ride long journeys the novelty of a loud exhaust gets old pretty quick.
Yes, I hated riding my bike with race pipes on it. So loud and practically gave me a headache after a 40 minute ride. Bought an Fz07 and I'm not touching the exhaust. It's so quiet, I can hardly hear it over the wind.
DThompson T I’m thinking of getting a FZ/MT-07. I’m torn between the Kawasaki Z650 and that one. What are your thoughts on the FZ/MT-07?
@@vexmau5 well, I went from stunt riding an F3, F4I, KAWI 636 then I stopped that and rode a 750 shadow for a few years. Now I have the FZ-07 and I love it. Is it the fastest I have ever had? No, but it's still fast enough. I love the low to mid range torque it has. Great for in town riding. The riding position is nice also. I looked up alot of reviews and riding videos before purchasing the Fz07 and nearly all were positive. Do you have experience?
DThompson T yes I do. I have nearly a year of experience with my R3 under my belt. I know it’s not a lot but I personally feel like I’m ready to move up the scale. Since I only have a year of experience, that’s why I’m looking at the Z650 and FZ-07. I’ve read all around that they’re good “beginner” bikes
@@vexmau5 I cant speak for the kawi but the FZ07 has good power, it's very light and its easy to handle. I dont know how "beginner" it is because it has enough pull to throw you off if your not careful but I started out on a 600cc and did fine with common sense. Dont act like an idiot with it and treat it properly and you should be fine.
"Any weight you can remove from your motorcycle is gonna make it handle better"
I noticed my DR650 was considerably faster and easier to toss into corners when I went from 280 pounds to 225.
Lol. Grats on the weight loss
Aye good on ya. I'm trying to lose some myself.
What do you weigh?
@@hughjaanus6680 225
Not ANY weight. Remove fuel tank and see.

Just taller and more ripped😁

@@emmanuelquerol He's definitely not more ripped. In great shape nonetheless, also around the same height
No homo...
His right arm is 2x bigger then his left.
What's wrong with you guys
I'm so happy with my stock exhaust. It's quiet and won't disturb anyone when I come home at two in the morning and it just sounds so sweet. It has a deep defined sound to it at idle and makes the bike sing at high rpms. But you can still talk over it and that is absolutely nice. Honda did a great job on that one. Also it really looks absolutely perfect. It's just has a stainless pipe for a muffler. I hate those modern round-ish looking pipes.
I got a 2005 CBR 125. Not big, but what a sweet ride I tell you.
@@jakob6399 His 125 "sings" har har har.
@@jakob6399 theres no questions about it not making it louder. It just does make alot louder, and if you disagree, you haven't owned a 125cc bike with an aftermarket exhaust.
@@jakob6399 I just put an Akrapovic exhaust on my ninja 125 and I can tell you, it’s loud, honestly a little too loud for my liking but it looks and sounds so much better than stock
keep up with my 636 tho, fuck the neighbors live your life nerd just be quick!🫣
@@jonahb8083 Wow. Real nice mentality.
love how short and simplyfied are these videos and yet you can learn so much from it!
I just want to praise Ari for his work, love his informative video’s which are efficient and not taking unnecessary time. Clear and to the point and very well presented. Sorry about your accident and you needed to stop. Thank you very much Ari!! Bless!!
yeah love those veins pop out when he holds a muffler
I am propably the only one, that likes quit bikes. It's so much more awesome to get around "undercover", cause everytime you drive or ride something loud, people think you are probably 10mph faster than you actually are. I've been in a Tesla once, and nobody thinks you are driving too fast, cause you barely make any noise. (Still not going for electric vehicles.)
Anyway, awesome vid Ari!
Agreed, just got a 2017 SV 650, this thing sounds awesome, but whenever i climb up to 50km/h in first gear, i see people turning around and looking at me like i was a maniac !
And this is with stock exhaust ...
Garrulus you're so right! I've Been hit twice in Los Angeles on my Motorcyle with a stock can because the ignorant cager just "couldn't hear me" ... After that I switched to aftermarket and haven't had any accidents since ! Why the fuck would anyone want to be "undercover" on a godamn Motorcyle ....
I get it! My friends tease me with my stock exhaust but i like being quiet. I don't see the need to noise-pollute whereever i go and when i go wildcamping it's nice not to alert everyone in a 10 km radius that i'm there.
As for loud pipes saves lifes, i call bullshit! Until proven otherwise i assume people haven't seen or heard me and act accordingly. When somebody revbombs to get noticed peoples go-to reaction is to see who the moron is. If you want to alert of a dangerous situation... well thats what the horn is for. But i see very few people bragging about their aftermarket horn, because you can't see it and it only makes noise when you need it.
Tor Thrysøe It sounds like you go riding in the woods a lot and don't commute through heavy traffic as I do on A daily basis... With my stock can, cars would veer into my lane constantly (that's how I got into 2 major accidents) which could has easily ended up deadly , but with my aftermarket exhaust that has all ceased and they actually move out of my way , because they can hear me , I did not get my exhaust to look or sound cool , I got it because I got hit twice and was not going for a third . Loud pipes do indeed save lives .
I commute to/from Copenhagen 2-3 times a week, usually when rushhour is at its worst. I ride defensively and don't make assumptions that people have heard/seen me until im sure.
I would not bet my life on people hearing my exhaust (which point the wrong way anyway). Heck, they can't even hear the sirens on emergency vehicles. Cars today are extremely soundproof. If i should mount something aftermarket to improve my safety (besides my aux lights) it would be a different horn.
I don't mind people using aftermarket exhausts (as long as they are not obnoxiously loud), granted they look and sound cool. It's not for me but to each his own. But i don't subscribe to the "loud pipes saves lives" notion. It's probably a discussion that will last as long as there are ICE motorcycles :D
Driving on LA freeways SHOULD be considered "closed course competition."
LOL..!!
racing tracks were designed because everyone is going the same speed roughly.
racing on the road where everybody is at different speeds is a death sentence.
but by all means.. add another to the natural selection list.. just dont take out anyone with you.
@@harleyme3163 it's called a joke.
@@harleyme3163 lighten up, man.
I bought the loudest exhaust system I could find the next day after lane splitting on the 101
Great video Ari! Nice touch cutting the stock in half for an insiders view. Keep up the good work!
Agree, I just slap on a slip-on any bike i use. Purely for aesthetics & a crisp sound. Modern bikes rarely need much performance enhancements unless you're seriously getting into racing. It tends to get very expensive to squeeze out about 3% - 5% extra ponies that have no real world benefit.
Better to invest in suspension instead, tires included. The bike will feel way different.
Another cool vid again btw.
Yep. If someone puts an exhaust on their bike but leaves the bald tires...
I guess different priorities than me.
gronkgrunk weight though
That’s due to headers. Adding a header with bigger ports plus slip on will increase almost 20% more.
OR on the R6 you could have your ECU flashed skip the power commander and have a far better engine breaking experience & smoother power delivery oh and it makes up for the 8-10% incorrect speedo issue at least on the 06-16 models idk about the 2017. My personal opinion.
Brakes and breaks are not the same thing. Much like your and you're. Think I'm being fussy? Well no because it is the difference between knowing your shit and knowing you're shit.
@@stephenpenniket9976 😂😂 so true
Ayyy didn’t know you rode motorcycles gundam
I like ECU flashes compared to fuel tuners as well
@@stephenpenniket9976 Lol.
Its funny cuz the your and you’re doesnt really bother me,but breaking vs braking for some reason does.
Maybe because it has to do with something technical 🤷🏼♂️
Really enjoying the show, informative on so many levels. The R6 factory exhaust is so plane Jane! Didn’t want a full system so happy with the idea of a muffler now. TY keep up the good work
MC Garage make amazing content. Each video is just the right length, presented fantastically by this guy and he really puts the info across in an interesting, practical, visual and easily understandable way. I mean, there's literally nothing else that could make it better. BOOM! Thanks guys, keep it up, bravo.
So you're his Dad? Lol
agreed, he does a great job delivering.
Always pair them with a tune. The end
And today engines probably run more lean than they could just because of emissions, if you are going to tune get a new exhaust too.
Chris Fokjohn ^ what if it's just a slip on?
if the cat is still in place you are ok with no tune
mintpaul not if you still improve flow, you need to then install a high flow air filter/induction kit and tune the ECU to tell the engine to adjust the fueling so it does not run lean or rich.
The ECU will adjust to a degree from the sensors detecting the changes but still can run lean/rich, plus you will not get any power gains withought a tune, the ECU will adjust to put out stock power. Just a rear box/slip on, you will not need a tune as it will not improve flow, flow is restricted by the size of the main pipe/cat.
Depends on how much the exhaust path changes overall. If you put a slip-on on the new GSX-R, you've made it a straight pipe essentially. If you put a slip-on on older gen S1000RRs then you should be fine without a tune
+Motorcyclist Magazine You guys are killing it with these videos, great job, as usual. You deserve a lot more subscribers.
holymolie not until they start cranking out more vids regularly.
holymolie quality over quantity
So where is the quality? Kid talks about backpressure like he's an engineer. A quick Google would have given him much scientific evidence that backpressure does nothing to improve performance, it actually hinders it. You want free-flowing exhaust, learned many decades ago.
Michael Cox Honda
Michael Cox peak hp sure a nice large pipe would be a good thing. But you loose torque. Crossovers in exhaust systems or headers by design may have some resistance to the exhaust to create a scavenging effect.
When I raced motocross, the only time I bought an aftermarket exhaust was for my 1988 Honda CR500RJ. It was to soften the off the bottom and midrange hire and give it better (longer) top end. It made life easier on the close circuit track as well as cross country and for the Finke Desert Race in central Australia.
Thanks for thorough analysis, telling us clearly pros and cons.
Your clear explanation no hype or speculation!
😊
Lmao "closed course competition only" I laugh everytime I read that on any of my exhausts
And the irony is that race courses often have more restrictive noise standards than the street these days...
really? that sucks
Yup. By "normal" street standards it would still be loud but not as loud as some of the pipes that people opt to run.
Durtur Hurbs yeah, the average Harley makes more of a noise nuisance than a race pipe.
it's all fun and games until you're involved in a big crash where other people get hurt and your insurance refuses to pay out by citing the always included undisclosed/illegal modifications caveat. just saying not hating 😉
The popping and crackling on deceleration is one of my favourite parts of riding my bike.
Myles Prower Yup. Too lean
Chuck M not necessarily. Can mean too rich, and the fuel is burning in the exhaust due to the air injection system (like my z1000)
@@Me-yh4uc Popping in the exhaust literally means the fuel went unburnt in the engine, which happens if you suddenly decelerate.
yeah must be so great wasting fuel.. I mean... lets just dump all of it in there and make a cannon out of it.
@@harleyme3163 it happens even on scooters, the honda wave i use to stroll around town tends to pop it's exhaust (not necessarily loud pops as the stock exhaust is so damn muffling, but pops nonetheless) specially after going high rev on a climb then suddenly letting go of the throttle for descent, specially if the engine is cold
Yep I knew, just try slip on for different sounds, no leaks no hastle . Get rid of box only before they start smog! Great vid💪 don't forget to rejet in my case or EFI box adjust
Y'all always got great tips thanks guys new Rider and I really appreciate what y'all do
I think its worth mentioning that even aftermarket exhaust companies are doing great advancements in this arena. Take Graves for example, not only do they make a great premium exhaust, but they also develop fuel maps and have optional sound suppressors for them. Recently they started selling exhaust with their own line of back pressure valves with custom back pressure mapping. Throw in their wideband O2 sensor kit and you really have an amazing performance package that's constantly adapting to the changing environment.. Its not just fancy plumbing these days.
Because a sportbike on the road, just doesnt make enough power.
Gotta hold it wide open all the time right? A 1000 can make 180HP bone stock.
Gotta spend 1000's to really make it go.
@@bradsanders6954 True, stock sportbikes are tuned for street riding and economy. To exploit its full potential at all engine speeds, need to spend $$$$$.
I bet it's going to become Motorcyclist Magazine's most viewed video for 2017! Even though we're early in the year and I enjoyed a lot MC's content so far. It's a theme enverybody has an opinion on, and your treatment of it is as clear & precise as when you slashed the debate on "will WD 40 destroy your motorcycle chain O-rings".

Has anyone seen the exhaust on a 2017 gsxr1000? I dont think anyone spent more than 5 minutes designing how that one looks.
+Tim Vine: Yeah, You could put a wheel on it and call it a sidecar. Ugliest exhaust I think I've ever seen.
Why worry ?
Nobody gonna leave it on there . . . . . .

Another great video... well done mann👍🏻👍🏻👍🏻👍🏻👍🏻
Nothin beats old school intake sound through big filter box and in-line carbs + a magnum exhaust on a ZXR!
I agree with your assessment and it's the reason I stayed with my stock Multistrada 1200S exhaust. A whole lot of money for virtually no power gains with the aftermarket kits. I do wonder about dirt bike aftermarket exhaust though. Now you don't have to worry about emissions and less about noise too although too loud is always bad.. Friends tell me a pipe will do wonders for my stock YZ250F but I am skeptical. Something I wish you would have mentioned in the video is that sooo many riders think that when their bike becomes LOUDER, it is FASTER, which is so UNTRUE in so many cases.
as emissions get stricter the gains that can be made from aftermarket exhausts will only get greater
which is dumb
Corvette Have you seen the 2017 Suzuki gsxr1000/r that can is not just huge. It robs about 5-6hp from the bike.
More like 10.
crisray6789 you mean like how modern emissions are tighter than ever but we now commonly have cars with over 500hp and bikes pushing past that 200hp mark? Emissions controls are one of the best things that ever happened to cars and bikes. Without them you'd still be tooling around around a carbureted POS smelling like raw fuel after a quick ride down the street because the OEM would have never had any incentive to improve the efficiency of the machines and spend countless millions on R&D making your bike or car cold start better, run and idle smoother, get better fuel economy and have more power.
Woha wait a minute here. Do you really care about fuel consumption while talking about motorcycles? (at tleast somewhat interestng ones, not scooters and sh!t) this is the last thing i care about. Better buy some 50ccm machine, if you care about every 0,01 l of petrol. I am proud ovner of 01 zx9R, and exactly because of those four big carburetors and overal simplicity and rawness of the bike, i will never sold her out. Just ram air intake, four cilynders, four carburetors, absolutely no electronic crap (shit like throttle control, abs etc.), and straight to wheel. You do not need neither diagnostics nor computer to properly maintain the bike, just a wrenchbox. And while talking about emissions,that is the absolute last thing i care about. I would gladly argue with you about those demonic CO2 exhalations (for simpletons, food for plants!) , NOx emissions (which are way lower from this dinosaurus that from modern diesels), or even that damn fuel consumption (4l/100km). Plus, the smell of that unburnt fuel exhaled through partially opened exhaust is quite pleasant for me, unlike that modern sterille machines. That somewhat not so smooth cold idle, or cold starts and such, for me, that just adds to the soul of my bike. You just need to know how to touch this machine, manipulate choke and throttle properly, know some basics of engine functionality, and you are perfectly okay.
As a car/truck driver I appreciate a louder bike simply because it gives me more heads up that a bike is around and allows me to try to be a bit more aware of what the rider is doing and where they are situated.
Thanks for sharing….!!! It’s best to stay informed….!!! Most people don’t know what they are talking about…!!!
Love your breakdown….!!!👍🏻👍🏻👍🏻
Excelent information , just chenged my mind on getting a full system for my mt09
Is it even legal to fart in California without some kind of state government regulation?
Well, I can kinda understand where they're coming from when you consider the serious air pollution problems which have plagued for example L.A in the past decades. Emission regulations put an end to that nonsense, because they forced manufacturers to develop ways to clean up the emissions to an acceptable level. I personally prefer having a quiet bike with a catalytic converter to having no bike at all.
They have crazy tight regulations but I've never seen any population of people who drive like gasoline is going out of style like California. Kind of did it to themselves all these years.
As long as you let loose in the Bay area they love the smell,they already have piles of s##t everywhere.
California politicians suck ass! Go TRUMP!!!
You have to fart into a tuba but WITH a catalytic converter installed.
I always pair an exhaust with a tune. Honestly though I go aftermarket mostly for the sound and weight saving lol. If you add power, your bike only goes faster. You save weight, your bike goes faster and it's easier to maneuver.
ap1986 ari mentioned that when fuel mixture is lean due to. change of exhaust it will pop when decelarating...
isnt that contradictory?
i thought exhaust poping when you decelsrete was caused by a tooo rich fuel mixture...
don trump : i might be wrong, but i am pretty sure the popping is due to a mix with too much air, forcing second ignitions in the exhaust. It isn't because of too much fuel.
That's at least why BMW 1000RR are popping all the time, or why BMW with N54/N55 engines (so 135i, 335i and so on) are popping SO MUCH : these are "fake" pops due to extra air purposely injected in the exhaust.
don trump my understanding is that it is more likely to pop because you're stock exhaust has baffles, your after market does not. So you're also getting an excessive amount of fresh air back in. Which you would've of had with your stock exhaust.
backfire through intake is caused by a lean condition or advanced timing, backfire through exhaust is caused by a rich condition or retarded timing.
Popping in the exhaust can be caused by unburned fuel on overrun, a leaking header gasket or burned exhaust valves.
Switching to aftermarket Cobra exhaust on my Honda Shadow was an overall good move. The stock exhaust weighed in at over 30lbs while the aftermarket pipes weighed only 18lbs total. The bike did run leaner after the switch, but a rejet and A/F tune fixed that. Best of all, a different but not necessarily louder sound from the Cobra pipes. Going from 1-5/8" to 2" tubing was a perfect step up all around.
On my 80s gt 750, my bike had an american made double skinned full length open pipes, they had a balance pipe, but absolutley no baffles, or sound reduction, took quite a long time to get the carbs re jetted, and needles in right position etc, ....sound was absolutey amazing, not just the usual rough loud spitting noise you got with drag pipes, this was a lovely quiet burble at low revs, blomblomblomblomblom😀, then opening it upgave you this incredible snarling deep roar, followed by extremely loud backfire pops and bangs on the over run😀
I always get a chuckle out of people spending money to make their bikes lighter when they, themselves, could stand to lose 40 pounds. Anyone that isn't totally fit should worry about that before they worry about shaving a few pounds off their ride.
I can't lose 40 pounds man i'd be dead
You honestly think that people spending money to make their bikes lighter need to lose weight? I weigh 12 and half stone and I'm 5ft 10in. My weight is perfect for my size. I wanted to make my bike lighter so it was easier to manoeuvre once I got off it, because I broke my collar bone and a rib after a nasty fall, and moving the bike down my garden path was a pain whilst I was recovering. Yeah I shouldn't have been moving it, but when there's no one to help you, you can only help yourself. Even after I fully recovered, I was getting pain for a while when the weather was cold, making me unable to move it as effectively. So I made it lighter. So don't laugh when people spend money on making their bikes lighter when you don't know the story, and don't say people need to lose weight because of it either. It makes sound like a complete dick.
itt: two people who can post comments but somehow can't read
Nathan Walker wtf kinda unit is "stone" lmao
Tomas right I’d assume 120 pounds 😂
I'd say improved sound is dead last on the priority list for a race exhaust.
Excellent information , thankyou. 👌🏻 from 🇦🇺
Good job Ari. Most info. Is useful. Good 'to the point' n crisp vids. Keep em goin mate :-)
The loud pipes save lives theory is interesting. I’ve been on a loud Harley and have had several people come into my lane. My sport bike was quiet. I hardly had any issues.
Sportbikes are more colorful so they catch the eye> luxury vehicles with fancy sound systems and other technical distractions
I experimented years back on my loud ass Buell I had at the time. If my pipe was BEHIND the driver, they couldn't tell I was there unless I really opened the throttle. So the whole loud pipes thing didn't do any good unless I was trying to attract attention...which a horn can do.
I didn't notice any change in driving behavior when I bought a new 1000RR and left it stock.
Great video I always wanted to know this information ℹ️ about swapping Exhaust and so on
Thumbs up 👍 Thanks
For sharing
Peace
Good video, very fair, unbiased and full of info.
The item that is compromised as much or perhaps more than the exhaust is the ECU. Reflashing it makes a huge difference, especially with Japanese bikes.
A lot of the reason for the "breadbox" is mass centralization, coupled with style considerations. Otherwise you a truly heavy and ugly cannon strapped alongside the swing arm, far away from the mass center and in plain sight.
Best vid I've seen on aftermarket exhaust systems. And, he agrees with what I've been saying for years. Thanks.
That exhaust in the video is built for emissions control. Put a aftermarket race exhaust on you immediately shed 30 lbs lowering your hp to lb ratio. Install it with a K&N filter and a tune for more fuel. Stock exhaust is ok but not better than aftermarket
You guys should do a video on backfire
*afterfire
Daniel Tilton that's normal
"My exhaust pops on decel FML kill me now", said no one ever.
Yeah, though my bike runs lean but I can't do anything about it since no one makes a fuel unit for it. I do however love the pops, I also enjoy the rare occasions when it pops and gargles all together instead of just a single pop haha
Death666wish I just figured out how to induce popping on my 750 on decel by just barely blipping the throttle continually, barely, and it will pop all day from like 8-10k down to like 5k ...i can't stop, like a kid in a candy store.....so much fun lol
I removed my stock exhaust on my GSXR 1100, replaced it with a Yosh pipe and it made a huge difference in power. Yosh had done a lot of R&D with Suzuki and the results were outstanding. It wasn't too loud, unless you got on it, so long trips weren't annoying.

I assume they are pretty easy to fit so a common mod for your average rider, but moreover I would be interested in other considerations in terms of the bike's 'brain' and if such a mod could reduce performance and increase engine wear. Love your stuff and keep it coming!
An exhaust system has been carefully selected for OEM, more than 35 years ago. Even in the 80s, sportbikes exhaust were fine balanced for emisions and such. They have never been an "afterthought" ( at least for high performance engines.) And "huge gains" isn't exactly true. An exhaust has typically been the most bang for the least buck. Even today. It's the cheapest item, within consumers reach with the most seat of pants feel. YES, there are higher performing items out there, that provide a LOT more power. But they are expensive, and you also have to upgrade many other components to get it to work properly. In the end, an aftermarket pipe will almost always provide a quick bump in power. No matter how good the stock exhaust is, it is there to balance, mainly regulations. If regulations of EPA emmisions, noise, and such weren't the issue, very few companies would be able to outdo a stock setup. Actually comparatively speaking, i think todays OEM while finely tuned, has more restrictions than yesteryear. ( meaning you probably see bigger gains going to aftermarket, then you did 20, or 30 years ago.)
Great info Ari, once again. Many thanks for your respected research.
Very informative! Slight issue with slip on is that they are not typically available to v2 vs. V4 engines. My cbr1000rr had a slip on yoshimura with power commander while my current tuono 660 had to be a full exhaust swap with upmap tune up
2019 MT10 here. I used some JB weld just on the tiny holes in the stock muffler and left everything else stock I got the sound I was looking for, For 10$ and some patience.
18 Wheels I think there are , at least every can or car muffler I have seen . I put on the Leo Vince mid pipe and love the sound now. With the stock muffler patched
depends where you ride i have a lot of small villages on my nice routes so having a stock exhaust helps to not piss of the locals and still have fun on the open parts with no houses
Great informative video - earned a new sub!
Thank you for an excellent and informative video.
Great cutaway of the stock pipe's cross-section. I've always wondered what's inside my Bandit's mammoth pipe. Now I know.
I love the stock system on my 95 Honda Dominator!! No way am I changing it.
Yes you are right on the money!!! Messing with the exhaust alters the power curve and does not always help the motor at the RPM range most people ride at. WOT maybe, race bikes OK free flowing. Just bolting a loud exhaust does little for the bike, but may make the rider feel it is somehow better. Vahroom Vahroom....
I have been doing motorsports all my life, and the sound regulations on track is actually harder on tracks in Europe then to be street legal, and although it is always a hassle to get there, it has made some manufacturers make really good preforming but silent systems, you can still get a meaty growl, but not the scream on high revs.
An easy way is to put 2 full flow dampers in series
Aftermarket exhausts sound great, but they draw so much attention. I'd rather go fast and sound slow than go slow and sound fast. I enjoy my sleeper =) And so do the people who live on the roads that I make my race track
More like draw so much annoyance :).
Drivers are distracted even more these days by phones, computer screens and often seem to just have their head up their arse. I prefer to have a little more noise from my bike so they don't kill me through inattention. I wear a day-glow vest and my headlight on constantly but still get inattentive knobs saying sorry, I didn't see you. I'd rather make a bit more noise rather than being super quiet. Not annoyingly loud but just to get the dozy one's attention.
Typical ignorant US-biker-attitude: Smart bikers just realize that you have to ride as if no one saw you.
I agree, I also like to fly under the radar while riding. You can hear a bike ripping it from a mile away with an aftermarket pipe.
Plus I commute on my bike and come home late a lot so I like to keep my neighbors happy.
Guess you never heard how that's nonsense.
if stock exhaust is that good why does yamaha have akrapovic on their site.
B/c of emissions. The stock pipe is impressive given that it navigates so many objectives, but that doesn't mean it's the best option for outright performance.
Because $
How is that even an argument?
Suzuki has Yoshimura as well ;)
@Vin Commons except many of these brands like akrapovic don't work out of their basements. They have collabs and tie ups with the bike brands to make exhaust for them. Why?? Stock exhaust has many limitations cuz of government regulations, performance is not the only objective of it.. sound, emissions, cost effectiveness.
Still riding the stock exhaust on my 2002. And it's the quietest motorcycle on the street and I love it.
Awesome Videos!!!! Does the Alpha T slip-on require remapping on a GSX-S750Z? Thanks
Sound is a huge factor when selecting an aftermarket exhaust for me. Pure music!
So what you're saying is I need to get an aftermarket exhaust
quick & great without all the nonsense bla bla ! love it mate ! u just got one more sub.
Great video ! Man 🤘🏼
I saw the muffler and thought, "Nice pipes." Then I noticed the absolute pythons this dude has and thought, "Niiiiiice pipes."
....yep....
Can you do an episode on lightweight wheels? stock vs ali/magnesium vs carbon fiber? are they worth the premium price?
camden thompson I'm a mechanic, it doesn't even require a mechanic knowledge to know that less weight on the drive train allows for an easier power application. It's just less lost torque/power. It's no wonder manufacturers try to shave off weight any way they can. Look at lotus, they don't have massive power in their engines but their car are lightweight, hence why they can chase the big cats on track.
Aftermarket wheels aren't good for a street bike as they aren't designed, nor can they handle, the stresses of potholes, long term use, etc... Race bike, they are great. Last I checked race tracks don't have potholes... lol
Not just power application, but agility as well. Less rotating mass, less gyroscopic effect, quicker turn-in and a "lighter," more "flickable" feeling bike. In my opinion, rotating mass is the top of the list in terms of weight shaving, then unsprung mass (wheels, brakes, suspension), then sprung mass. If you can get unsprung and rotating mass down with one change, that's even better. This is why I downsized to 14" wheels for my track MR2. At 11lbs. per rim compared to 12-14lbs. for a 15" rim, that's a very noticeable difference on track.
The Lotus Elise (there's one at the shop now for a clutch) is a ton of fun to drive even with it's modest 210ish hp. We probably won't dyno this one because it's stock and there's no point. The Lotus Esprit (my shop's owner has two) isn't nearly as light or as small but it's still very fun to drive. Still very British though, so it essentially takes an electrical engineer to fix an electrical issue on it. And those issues are very common.
I guess DOT approval and 122K miles on the street would make carbon fiber wheels no good? www.brocksperformance.com/brocknm/templates/bpp1.aspx?articleid=797&zoneid=1
If you can get the same strength for lighter weight, you'll be faster off the line, and feel more agile going into a turn. The gyro effect of the wheels.
That was a wonderful video and informative. I would like to know what happens to the O2 sensors when you install an aftermarket exhaust. Can we somehow still use the O2 sensor as it helps the fuel adjustments job as explained.
Cheers!
You have to reinstall the O2 sensors, if you install an exhaust system that doesn't have provisions for them then you'll have to buy O2 bungs (local automotive parts stores and catalogs like Summit Racing, Jegs etc have them) and cut a hole(s) in the pipe(s) and weld them on, any system that uses O2 sensors needs them for the computer to run the timing and injectors correctly, eliminating them will send the computer into a "by-pass" mode and performance will drop dramatically.
Lots of informations that are truly helpful
Slip on mufflers make noise. Full systems make power.
Slip-On mufflers can add power too, but only few in comparison with a link pipe or even a full system.
not always true, I gained a pretty massive 12 hp on my Bandit 1200 with M4 slip on and K&N filter.
@@ljoelmchanley3676 and no tune?
If the bike is tuned they will make power. Most people forget the bike needs a ecu flash(very recommend) or the power commander route(more expensive) to get the full benefit of the full system.
Ljoel McHanley I’m not convinced you gained 12hp with just a slip on and a air filter with the stock system still in place and no tune, unless you put a video out of some hard numbers from a Dyno then I can believe it. I’ve had to flash my ecu, put in a full system and k & n air filter to draw that kind of hp from my bike around 15hp boost on my bike.
If you tune with a power commander you might as well not tune at all.... You have to get your ecm flashed or swapped with on OTS tune/ecm or get your bike on a dyno and get a custom tune.
I purchased my NC750X from a dealer and used it for comuting 50 miles each day in mainly Motorway traffic. At the first service I mentioned that the performance was not so great in second gear, sport mode, at low revs and far worse in eco mode. They recommended the fitting of an Akropovic aftermarket silencer saying that this up the performance would impress me. It didn't.......the unit did weigh a few pounds less but apart from being a little louder the low rev performance was still dull. On checking the maker's own performance figures, for my £600 pounds I had gained a mere 1/2 hp.
super informative , thanks for exhaust lesson
weight off the gut should be prioritized imo. :)
Forrest Shalom slimfast is cheaper than carbon fibre!
slimfast is rubbish. slim down permanently and sustainably with cheese.
@@jamesforrestal403 I hear starvation is cheaper
5:29 it sounds so nice!!
thank you for breaking it down to simple terms
Great informative video. I wonder if the same holds true for Harley Davidson’s?
*LOL as if we care if its street legal 😅*
Night Rider exactly
I do
PetrosRZ i don't
And I've yet to ever get a ticket for any aftermarket exhaust, in 40 years of riding. UGLY stock exhaust is the first thing to hit the scrap yard. I don't even bother to keep the UGLY things.
run that exhaust in the EU and u will get fucked if you crash cause the insurance isn´t gonna pay a dime. plus you will get stopped after every ride and get a ticket
Loud exhaust lets the cops know where you are. I prefer stealth.
Yes 100% but the upside to that is it makes car, truck, bus, and pedestrians aware of where you are.
Or getting smacked off your bike because someone didn't hear you
I put an Akrapovic complete exhaust on my 1999 R1. There was a saving of 5lb in weight, the power gain may have been small and yes it was noisy, but it altered the personality of the engine. Before it would rev, but it preferred not to. After it loved to be up around the red line. I was so in love with that bike, I only sold it last year. Now I ride a 1290 SAS: civilised, quiet and easy to ride (with the traction control on) much better suited to my 73 years, but that R1 was the best bike I ever owned.
I got an old Honda CB400 SuperFour a few months back.
I bought it as a gift for my son to get him to go for his Full bike licence as he has been on a 125 for his 3rd year now, plus it sounded amazing!
He has annoyed the hell out of me and so I thought bugger it, I will use it.
Annoyiungly, I should have double checked the exhaust because even though it looked great, I have hardly done more than 200 miles and it started to pop, on close inspection, I found a hole in the No.3 downpipe... I took the exhaust off to get a proper look, and lo and behold, I find one of the rustiest setups that I have EVER seen, and after sopme wire brushing and trying to clean it up, I have come across more holes than a sieve... Thick coating of paint was all that was holding it all together!
Even worse, is that the collector box, downpipes, and silencer, are all welded into one single piece and so even though the silencer is ok, I cannot get it off ( Might cut it and make a new connection )
I am however hoping that I can still save it, at least for long enough to let me have a couple of years use out of it.... I doubt it will weld although I got a mate who says he can weld anything no matter what, so lets see, but if not, I hope that the Heat resistant SteelStik will be my saviour.
I have been told its good stuff, but does anyone have any experience with that?
The holes are all just on the top of the bend on the downpipes... At the back... A few holes have appeared right after the join where it goes into the head port, and some are right on the corner, on the inside of the bend, and the farthest downm, there is some little holes about 4 inches, in total, on the two inside pipes, there is 12 holes, the largest is about 3/4 of an inch, so quite sizeable, but most are 1/8th of an inch give or take...
I also have a couple of tins of Simoniz VHT Spray.. Rated 800c.
Does anyone know roughly how hot the exhausts downpipes get on the CB400 SuperFour?
Its a shame because the bike overall, is an amazing little thing that is small for sure, but so much fun to blip about on!
Peel the stickers off and no one will ever know
My M4 slip on for my 636 gives me eargasms every time.... :)
I'm planning on getting one soon. Maybe next month. Haven't heard it in real life yet, but it sounds pretty fucking sweet on TH-cam.
two of my friends have the M4 slip on exhaust, decat with power commander on their 636's. Sounds absolutely amazing
JustGamer haha, Yeah me too! I love the m4 gp slip on on my 2016 Suzuki gsx-s1000, it sounds soooooo good😈
JustGamer i
C Stephenson Suzuki, damn you're one gay nigga
I got my 2018 CBR 1000RR in 2019 and it has 18,000 miles. I put Akropovic full exhaust , power commander V, K&N Air Filter and Dyno Jet Auto Tuner. The bike runs well and has a amazing response.
In MD as long you own the bike it doesn’t has to be inspect it. Since it doesn’t have catalytic converter it would be hard to sell it and because of it and the fact I love that bike I am keep it.
Great vid man
Factory exhaust gives a smooth feel during long runs and sound proof journeys whereas the aftermarket exhaust gives growling sound at idle and farting sound on high revs plus the extra sound hammers the brain in the long journey but that's good enough for mindless dudes.
watching this while installing a full system
Charlie Rodger do you really need to change fuel and air mixture when installing full system ive bought a full system for my honda cb125F and im curios if it will work well
Excellent video that gives well deserved credit to the OEM designs
I'm looking into IXIL exhaust for 2019 Yamaha MT-07. Are they any good? I like the sound of that better, but can't find a descent review of the pros & cons.
Why cant they put effort to make the stock exhaust look nice and sound good? That after market exhaust looks and sounds waay better
msaleh93 "sound good" is a subjective term my friend what might sound good to u, may not sound good to me. its just like music.
looks again depends on the make and model but in general most of the aftermarket pipes have a tricked out looking muffler. I think the manufacturers don't want to make the bike more expensive just for a nicer looking exhaust.
msaleh93 the only sport bike stock exhaust looks good are s1krr,r6,2012 cbr1000rr,they all looks sharper,smaller
its mostly to do with cost, sound compliance, and emissions compliance. they want to make a single exhaust compliant with as many countries as possible so they have to design it around the harshest emissions and sound regulations. if they have to make multiple exhausts for various countries then it adds cost on their end which they then pass off to us when they sell the bikes. It always comes down to money and what the company needs to compromise in order to get the most money out of a single machine.
Ducati does well on their stock exhaust
The aftermarket exhaust sounds better because it doesn't have to comply with noise or emission regulations, just like ThriceIND said. Also, manufacturers can cut the prices of their bikes by not having to install long, unnecessary exhaust pipes. The breadbox takes care of the noise and emissions, so just a short stub is needed. Most customers enjoy a bike that's cheaper than its rivals, which is good for business if your bike is the cheaper one.
Loud exhaust helps cops find you when you're trying to run from them....
Never been a problem for me.
If they can hear you, then you're driving to slow ;)
@@MetallicaSindre Never been caught yet since 1992 and I run an akropovic on my zx9r and a hindle on my R1. Hearing me is the least of my worries when I am riding.
Excellent description and video.
I can see that you really know about what are you talking about... excellent!!
