On the issue of fuel in modern fuel injected cars the only thing you can change easily to gain a little power is to run clear gas IE no alcohol in it can help. To running e85 and get more power you need bigger injectors, a tune and probably bigger or a second fuel pump because it takes a lot more volume of fuel.
1:47, haha, I’m 48 now but when I was 20 (low rider phase, extremely low budget) I cut one whole turn out of all my coil springs on my Geo Tracker! Haha, it looked cool as hell but rode like 💩
I got rid of the stock mufflers on my 2019 GT because they sound tinny. I added the MBRP Pro series race exhaust, and yes, the cold starts are loud, but I didn't delete the resonator or cat. So it's loud. But not abnoxiously loud.
Don't throw on certain mods without a retune. So true. I bought my 2018 Mustang GT that was already modded with a JLT cold air intake, among other mods, and although it ran ok the check engine light was on and it was throwing engine codes. I did some research and realized the prior owner likely didn't retune the car so I bought a Bama RevTech tuner and did a 93 octane race tune based on what mods I had. That cleared up the codes and of course opened up the performance potential from the factory tune. It's been running like a 500 hp beast ever since.
I said back pressure but what I was trying to explain was scavenging and I used the wrong terminology. There are absolutely cases like turbo cars where running wide open is beneficial, my point in the video was not to remove the mufflers just to make your car loud.
Wow, I don't know how to respond. First. I've been racing for over 40 yrs. I run my own shop and do 100% of my builds and know what works and what doesn't. Next, a lot of high school kids don't have money to spend and do things right unless they have rich parents and spoilt. Life is about trial and error, and that's what test and tune nights are all about. So telling people not to do things, they aren't doing any of that. Kids don't have $100k to build a car perfect from the start. I've ran plenty of stock cars on both turbos and nitrous and had little problems after I found the weak points. Race fuel will help keep your engine alive when you add a turbo with high boost. If you just get told what to do and never test and try for yourself, you never learn anything. I don't want my kids to put slicks on and hook up on the street, thinking they are in full control. I want them to spin to learn to control the car and lean into controlling the speed.

I don't want some scientists to tell me something won't work because he never tried it and was always told it won't work. I wouldn't be where I am today if I listened to what people told me not to do. Now those people call me to fix their problems. Yes, some of the things you don't want to do.

Cold air intake lol 😂 90% don’t have larger MAF sensors hence the reason most have little to no advantage for getting them other than looks. My favorite argument I hear is guys saying the metal ones are the best.
See it often about the Race Gas/Premium in a stock car. Actually, MotorTrend made an EXCELLENT video comparing different grades of gasoline and race gas in an engine and showed the horsepower differences. It was all the same because the car wasn't turbo/super charged. If you cannot make use of a fuels ability to avoid Pre-Detonation then using a higher octane fuel doesn't do anything for you.

Great video 👌🏽. When you were going over camber, I cringed at the tires on that import. Why these dudes stretch a 235 over a 10” wheel I’ll never understand. Safety first
Hi, wondering how to contact CJ Pony Parts Customer Service, I've trouble with my order and I have not had an answer to my email for 10 days... Please tell me what to do
I definitely agree with a few things you listed but when you say your car wants back pressure, that is absolutely false. You have to take into consideration volumetric efficiency. Back pressure doesn't allow for proper exhaust scavenging. You want as little back pressure in your exhaust system as possible. Ideally under 2 PSI. Anything more than that and you're losing power.
I said back pressure but what I was trying to explain was scavenging and I used the wrong terminology. There are absolutely cases like turbo cars where running wide open is beneficial, my point in the video was not to remove the mufflers just to make your car loud.
If a muffler adds back pressure it's hurting power. There is never a performance gain with back pressure and I hope people, especially professionals, stop saying that. If the muffler flows as much as a straight pipe then it would not add back pressure. What might be the case is that deleting the muffler hurt velocity and therefore hurt power. Even though that's rarely the case. Also turbo engines most certainly don't want any restrictions in the exhaust. Blanket statements make the world a bad place
I said back pressure but what I was trying to explain was scavenging and I used the wrong terminology. There are absolutely cases like turbo cars where running wide open is beneficial, my point in the video was not to remove the mufflers just to make your car loud. My bad
Im no expert in exhaust, but I still find it odd that you have open headers on cars and aircraft (think a P51 Mustang etc). That was for maximum peak rpm power.There is never any mention of backpressure requirements for those applications. I cant find a decent example, or a study that really dives into this. Any good places to start? Thanks. Good tips indeed, just this point is very muddied by people that do a thing, and then want to justify said thing. I still like to learn new aspects, no matter how much I may know in one area etc.
I said back pressure but what I was trying to explain was scavenging and I used the wrong terminology. There are absolutely cases like turbo cars where running wide open is beneficial, my point in the video was not to remove the mufflers just to make your car loud.
@@cjponyparts Got it. Happens to me too when I switch terms, reverting to the one I used longer, even if less correct. I admit that exhaust has been my weakest area, where the resonances due to length of pipes always throw me off. So, if I ever design a car...Ill just have eight straight pipes going to some basic muffler then out the back like a B52 lol
The muffler part is a surprise to me, but I do have one question for a part I will install soon on my 14’ gt. I will soon add the Corsa Xtreme Axle Back Exhaust, but I do not have the resonators anymore, would that still be okay for the car?
@@TheDuckTeamYT i am agreeing with you and making a sarcastic joke. Most people at the strip are trying to squeeze every hp out of their build. Im sure if open headers were really hurting hp 90% of drag builds wouldnt have fender/hood exit exhausts😂
I said back pressure but what I was trying to explain was scavenging and I used the wrong terminology. There are absolutely cases like turbo cars where running wide open is beneficial, my point in the video was not to remove the mufflers just to make your car loud.
You must be a human Dyno NOT! Deleting the mufflers, absolutely makes more power, although very obnoxious on the streets, especially with boosted applications, the resonators kill the most power, and mufflers only help with torque near the bottom on smaller cubic inch motors the more cubes the more boost the more it likes free flowing, exhaust unless every Dyno I’ve ever run or seen on earths wrong??
1:11 back pressure doesn’t add any power. In fact back pressure is terrible for power. You’d think that someone like you who claims to be a professional would know that this is the case…
Not true back pressure creates suction which helps exhaust gases escape faster. Theres a sweet spot for each engine when it comes to diameter of the pipes. Too big and there is no suction at all and too small there is too much restriction.
@@luismelchor744 Yes the whole point is to maximize the velocity of the exhaust gases. And you are right that back pressure creates velocity. If you have air escaping in a wide pipe the pressure difference between the gases in the pipe and outside in the atmosphere will be smaller and thus the air won’t escape as fast and might actually cause some exhaust gases to travel back (newtons third law). Generally speaking to maximize velocity you want to minimize pipe size changes in your exhaust and smooth out turns. Sharp turns are really bad and are going to rob you of power. Catalytic converters too cause back pressure, yet the only benefit of them is environmental, it don’t help in any way with improving engine efficiency. This is the main reason why saying back pressure is good is wrong is because it’s a misunderstanding of this velocity concept. Yes back pressure can help increase velocity but it can also do the opposite in cases like tight turns in pipes ect.
@@luismelchor744 And honestly if you have like 10 minutes to spare, instead of reading my reply, watch either the MotoIQ video on this topic or engineering explained. They both do a great job explained the physics - honestly a much better job than i ever could.
Back pressure's is never good for an engine, That myth has persisted since Karl Bent first invented the automobile in 1885. *Leaded race fuel is not going to hurt your engine. If you dont have the money to lower your car/ truck and are willing to give up the ride comfort for what you want, then heat or cut you springs be a man. (Using leaded race fuel at the track will eventually clog your catalytic converter and O2 sensors. It would take a lot of track days for that to happen. Its not recommended for every day use because of that reason)
I said back pressure but what I was trying to explain was scavenging and I used the wrong terminology. There are absolutely cases like turbo cars where running wide open is beneficial, my point in the video was not to remove the mufflers just to make your car loud.
shiiiit i had mbrb axle back & then added catless headers & there was no difference, didn’t sound different or better- then i deleted those mufflers & i love it lol. get compliments all the time but then again, yeah it’s my car 🏌🏾
@CJ Pony Parts I know I'm being hyperbolic...I know "safe camber" exists but no one and I mean no one ever gets a professional analysis done before stancing...
Back pressure and power do NOT go in the same sentence… this has never been proven EVER Unleaded Race gas DOES NOT BURN SLOWER… the octane rating is the fuels resistance to “pressure ignition” or “pre ignition” even when switching from 93 to e85 your timing tables DO NOT CHANGE unless your engine is spark limited by boost or higher compression ratios, but thats because of the octane not the flame speed!
@@hieronymus..bosch8532 absolutely not true. The motor if not knock limited will make the most power at the same timing whether it's on 87 octane or Ethanol or methanol. Also if you tuned to 13:1 on pump gas and then drain and refill with E85 you would then see it run lean and tune it right back to 13:1.
@@randyschmidt19 the air fuel ratio is drastically different & that requires a different tune , even if they use the same timing maps, as alcohol likes more timing but it isn't necessary ?
@@hieronymus..bosch8532 oh my god alcohol does not"like" more timing. You are right that the "tune" is dramatically different. It takes 30 to 35% more fuel than gasoline. That's it. Unless you didn't set the timing right the first time, changing the timing on alcohol will yield zero results. Any time on the Dyno would show you that.
@@whpony96 this is a very false statement lol. I know the epa is on everyone these days but if your car is properly tuned for the mods it's fine and when you're running big power like 800 rwhp with a power adder cats can actually cause issues if you blow them out in some cases if can clog up your exhaust and cause severe engine problems. So that is a very untrue blanket statement. It will smell little bit more but if it's properly tuned it won't be that bad and on e85 it'll actually be cleaner than a bone stock car.
The "Don't mod unevenly" part is so true. Why I cringe when I see these dealerships slap a blower on a base model GT with standard brakes and all-season tires.

I said back pressure but what I was trying to explain was scavenging and I used the wrong terminology. There are absolutely cases like turbo cars where running wide open is beneficial, my point in the video was not to remove the mufflers just to make your car loud.
Well explained sir 👍🏻👍🏻👍🏻👍🏻🌹
Thank you!
الله حيووو 🇴🇲❤️
I pretty much keep my car's stock just go out and enjoy driving it the way it is.
I know many Foxbody folks who have cut their springs lol
The fact that most of this has to be stated …
shiiiit i had mbrb axle back & then added catless headers & there was no difference, didn’t sound different or better- then i deleted those mufflers & i love it lol. get compliments all the time but then again, yeah it’s my car 🏌🏾
My 2018 Elantra Sport has no muffler. I bought it like that. I think it may have the resonator. Sounds good too.
you missed the perfect opportunity to stand against "stance" its dumb and dangerous especially if the car has any sort of power.
That was the "Too Much Camber" part of the video.
@CJ Pony Parts any camber is too much especially the drive tires.
@CJ Pony Parts I know I'm being hyperbolic...I know "safe camber" exists but no one and I mean no one ever gets a professional analysis done before stancing...
Back pressure and power do NOT go in the same sentence… this has never been proven EVER
Unleaded Race gas DOES NOT BURN SLOWER… the octane rating is the fuels resistance to “pressure ignition” or “pre ignition” even when switching from 93 to e85 your timing tables DO NOT CHANGE unless your engine is spark limited by boost or higher compression ratios, but thats because of the octane not the flame speed!
E85 air fuel ratio is different though than gasoline , 9.7 to1 so fuel maps are different & timing should be too
@@hieronymus..bosch8532 absolutely not true. The motor if not knock limited will make the most power at the same timing whether it's on 87 octane or Ethanol or methanol. Also if you tuned to 13:1 on pump gas and then drain and refill with E85 you would then see it run lean and tune it right back to 13:1.
@@randyschmidt19 the air fuel ratio is drastically different & that requires a different tune , even if they use the same timing maps, as alcohol likes more timing but it isn't necessary ?
@@hieronymus..bosch8532 oh my god alcohol does not"like" more timing. You are right that the "tune" is dramatically different. It takes 30 to 35% more fuel than gasoline. That's it. Unless you didn't set the timing right the first time, changing the timing on alcohol will yield zero results. Any time on the Dyno would show you that.
@@randyschmidt19 that's my main point the tune is different for fuel but it might vary with timing between methanol and E85
Deleting the muffers or cat's is bad. The louder noise will attack the Police to pull you over.
I was about to remove the catalytic converter but now I decided to keep them 😪 .
Working on any car without cats will make you quit working on it quickly.
@@whpony96 this is a very false statement lol. I know the epa is on everyone these days but if your car is properly tuned for the mods it's fine and when you're running big power like 800 rwhp with a power adder cats can actually cause issues if you blow them out in some cases if can clog up your exhaust and cause severe engine problems. So that is a very untrue blanket statement. It will smell little bit more but if it's properly tuned it won't be that bad and on e85 it'll actually be cleaner than a bone stock car.
@@midnight347 GT500 Makes 760HP with all the emissions in tact....Nice try.
and last but not least, don't get a bama tune
Good alternative?
@@reddbull9772 lund, venomous tuning, pbd, vmp. basically anyone other than bama
@@stevenhinckle7597 i got bama rn is it possible to still get lund nguage device ?
What’s wrong with bama lol
What car? Im too poor to even afford a Dodge Stealth or Geo Metro. 🤣
😂 yeah I Interpret this at cheap car mod list, thanks
Been cutting springs for 20 years. If done correctly you can keep 90% of original ride quality. Better than 90% of aftermarket springs.
A towel is going to scratch the paint? Well, maybe with the Mustang paint that actually might be true.
A towel will absolutely scratch your paint, any paint not just mustang paint. This is why they make microfiber paint safe towels to dry your car with.

Excellent vid Bill
People cut their springs still? I thought that was like 90's hatchback civics that do that.
The "stance" crowd kills me 😂🤣😂🤣😂 like how do they think it looks cool 🤮🤣😂🤣😂
More back pressure has never given more hp. Total fake news.
