EXHAUST POP how to - super simple guide for POPS and BANGS
ฝัง
- เผยแพร่เมื่อ 16 ต.ค. 2024
- After publishing a video every Sunday for 30+ this Sunday I decided to do something super simple and take it easy for a day or two. So I retarded my ignition a bit and squeezed a few pops from my exhaust and decided to explain a bit of the theory of making pops and bangs / exhaust popcorn/ pop and crackle, or whatever else people call it. It's a super simple and straightforward guide that will get your exhaust popping in no time :)
A few additional notes when it comes to exhaust pops and carburetors:
In my case the Nodiz doesn't allow negative ignition advance values (below zero), and in many cases you want negative values for bigger and louder pops and bangs from the exhaust. This is part of the reason why the pops you can hear in the intro to the video are pretty mild.
Also for louder pops and bags with carbs you will often want pilot jets that are a bit larger than is recommended for good idle air fuel ratios, this means that your mpg may be suffering in the interest of pops and bangs. This is the other part of the reason for my mild pops and bangs as I didn't touch any of the jets on the carbs to get the little pops.
For maximum pops and bangs you also want the engine as warm as possible, the pops and bangs will often be loudest during hard driving when the exhaust manifold gets very very hot. Cast iron manifolds usually produce inferior pops and bangs compared to welded steel manifolds.
Thanks for watching and much love to you all!
A special thank you to my patrons:

I love your videos so much because you don't just explain how to do something, you also explain why it is important and how it works
Was thinking of this not even 30 minutes ago, beautiful timing

Illuminati ?
I like to think about combustion that actually does work
Now, that I have noticed the "BIH" on your number plate, I respect your english a lot more lol
What country is it?
It´s obvious he isnt from a native english speaking country
@ I always thought he was german because of how he pronounced german words in his "iconic series"
@Martin M I agree. There actually is people out there that cares about more than just his/her native language. It's welcome. (Compared to RU for example)
Good catch. I thought he was Italian.
I had a lot of pops and bangs last night after having Taco Bell.
13 taco afterpoop 🌮🌮🌮🌮🌮🌮🌮🌮🌮🌮🌮🌮🌮💩💥💩💥💩
Bro I ate taco bell in bed now I feel like shit this morning
MrBooshScadoosh lmao I typed the message above you when I was drunk off my ass eating taco Bell lmao littyyyyyy
Haha!
😂😂😂
My viewing of this video was more for entertainment than wanting to replicate the effect - love car stuff and anything presented by you... but as you predicted, I also learned more about engines from your explanations of how this effect is achieved and the differences in fuel delivery between carburettor and injection engines, aaaand a little bit about engine mapping / ECU control which is very new to me. Thanks for once again making something that educates and entertains!
A moment of silence to electric car owners. 🕯
A few weeks ago i heared an electric Renault Zoe and a new Nissan with gasoline engine. Gues wich was louder. Jetzt den renault with These artificial Sound. Cant Imagine the whole street with these moving Soundmachines.
What about those of us driving nuclear powered cars? :D
Nope. Aint getting anything for electric shizzle from me. Sorry.

I'm so glad you have brought this up. I'm currently fitting a Nodiz and CBR900 carbs to a Pinto in my kit car, and have been looking at how to get pops and bangs.
You've shown me the way!!!
Love your channel dude
When I was a kid I used to turn the engine off and the back on while driving. That is untill I blew the muffler up.
Luckily your steering lock did not engage
I have a 99 Ford Ranger with the 2.5L inline 4 cylinder. It has 2 spark plugs per cylinder and a lot of pops when I get off the accelerator. I removed the catalitic converter and replaced the muffler with a Cherry Bomb glasspack. It's a Beast!
the pipes are small in diameter, sounds like a vacuum cleaner... but yes i hear the pops.
Šteta što nisam ranije otkrio ovaj kanal.
Ima se svašta ovde.
Having a combustion outside your internal combustion engine is a big brain move if you ask me!
The way I did it with a distributor ignition and fuel injected engine, was putting a straight through exhaust with a big bore on, and just tap the throttle on engine decel around 4000 - 5500 rpm (generally with the clutch in)
Well, for my carbed moped with de-waffle-ed muffler, warming up the engine and the exhaust, revving to the top, holding gas fully on, and switching ignition on-n-off made it pop n bang and shoot flame, because, of combustion igniting on hot exhaust pipe.
Switching ignition helped fill exhaust with unburned air fuel ratio, then it all to combusted with the heat of combusted hot exhaust gas. Simple. Ohh, and btw, yours is carb'd
what about kill switch, lightly press it and pops should come cuz spark plug doesnt fire when it is pressed and gas goes to exhaust. Check my channel i got monkey with 125cc swap and when it wasnt adjusted properly it shot flames crazy and now it doesnt pop etc at all cuz it is running good...
@@j0lel666 Saw someone who made 2step with a shift light triggering a relay to disconnect the coils, popped like mad
Looking at getting an MR2 mk1 tomorrow! Super excited
So for anyone watching videos like this and thinking they should do this to their cars, you should really understand why anti-lag is a thing and why you REALLY don't want to be exploding fuel outside the combustion chamber. Its done as a NECESSITY and not for fashion and "cause it sounds cool". If you like your exhaust sounding poppy and crackly I hope you like the sound of your money being dropped down a hole too because you'll be replacing parts a lot more often. :)
I simply can not resist commenting after seeing your number plate very good looking project car and i see there is lot of mechanical engineering involved brate. I appreciate your English. Vrlo dobri videa i samo napred, ja mislio da si negde iz Germany ali tako nesto. Pozdrav iz Makedonije
we love your all video boss, thats all very helpfull, thank love and respect sir
Ате братеее ти си босненски началник. Хвалааааа
man, your explanation is veary detailed and excelent! yhanks
Great video mate!!! Cheers! I heard some more intake sound too, did you change air filter too? Or was it just the position of the mic?
No air filter on the second shot. You've got good ears man!
If you wanna real good pops and bangs, just adjust the carburator to lean. Its not for permanent use but gets you some impressive bangs and even flames.
Another great video.
I hate aftermarket pop and bang maps, extremely annoying!!
Seems like everyone around my area has them.
Oem pops and bangs and burbles on the other hand are a totally different story, Porsche Panamera turbo a case in point!
Who doesn’t love snap,crackle, and pop exhaust sound?
I when they are fake
Radiš odlične videe!! Svaka čast! Navukao sam se, a sad kad vidim da imaš BiH regu još si mi draži!!
for the EFI bros, sometimes just putting some tension on the throttle cable to open the intake just a tiny bit, and that can make your exhaust pop
awesome video...my car seems to pop when i let off the accelerator and free wheel...is it bad for the engine...stock 4 cylinder 1800 jetta mk2?
Hi there. Ive got a 2014 Ford Figo and ive just replaced the water pump, thermostat, radiator and cylinder head gasket. My problem is its overheating so badly and i dont know what the problem is, i have tried everything i can think of but no luck. please help.
Really good stuff man! I appreciate that you took a kind of dumb topic and fully explained what's going on. Thanks!
Thank you Gru from Minions!
Very clear and good video!
It would be cool if you could make a video on the Xu series engines especially the Xu9j4 from the peugeot 405 mi16 or the groub b 205 t16 as they generally get very little attention.
Keep up the good work!!
T16 is an absolute beast
What about diesel popcorn? Also ... could you please explain why some diesel engines tend to do the "pow" sound when you release the trottle? Thanks m8, amazing vids
Yo would I just be catless if my cats burned through or would it actually cause damage? I don't mind going catless without paying $1k for catless headers
Your car is carbureted but you have a ignition ecu how? Pls explain thank you 😊
I like your videos but this time when you said going frome this to this it was really funny because i didn't notice any differences even tho i always had a loud car with pops and cancels :D
Your 0 degree spark is still occurring way before the exhaust valve opens, not after it has opened as you suggest. Ignition must still be happening in the cylinder but continuing as the exhaust valve starts to open. A rich or weak mixture may also be slowing down the combustion process.
Please clear me one thing.
You mentioned about distributor ignition system. It works in cars. But what is the name of the system used in older carburettor motorcycle which don't have any ECU ?
Really good explanation!
You got a new sub
Thanks for these infos ! Keep it up please !
Do you know if you'll do a "iconic engines : what makes it great" about the XK engine ? :]
Yeah AJ (XK succssesor) engines too, they are relevant for 20years.
excelent man! thanks for the explanation!
Wouldn't a bang/backfire be an actual detonation outside of the combustion chamber, where as a crackle would be something like an exhaust valve opening too early and the combustion continuing out into the manifold?
Good job man
I really appreciate the informative video. I only learned very recently that people love those sounds and in truth they always made me a bit nervous perhaps because I once read of fuel igniting in the exhaust and blowing something apart, maybe the manifold. It was a long time ago but an undesirable and quite unforgettable outcome nevertheless. On top of that, using fuel without getting propulsion is an uncomfortable idea since it represents money that could go to gaskets or paint. I'm a practical man, which is why I only replaced my steering wheel twice.
Hey cbr600f2 carbs, great man 👍🏾
I feel for our grand kids who will be listening to electric motors 🤭
I mean, there are people who like loud supercharger whine and can't even hear the exaust, it'd probably be a lot like that.
Does this damage the engine? or only the exhaust?
I want to do this where if i go above 4k rpm I can release throttle for some pops. Nothing too crazy because of Cats, and i believe Texas does a emissions test, so, that is important not to fail.
Love it !!
you ever do a vid on the effects of shaving the head/block on a 4AG? how about degreeing a camshaft?
Shaving how much?
And what camshaft.
@@fastinradfordable pick a cam TRD 256 to maybe a TODA 320?, head maybe .005 thou?
Degreeing the cams on an AW11 is a real pain
Very informative and well presented. Magic!
Fun Fact: On a stock small port 4A-GE with map sensor and no cat, it will pop and bang when you set the timing right.
Set the timing right?
Or wrong.
educational and entertaining;Quality content
Tbh I thought the exhaust sounded the same lol
Au pa ti si nas jebote😅Samo nastavi legendo, najaci si💪
What ecu program do you recommend for JDM cars
its easy todo on a 2004 Skoda Octavia with the 2.0L inline 4. just cut off the muffler and boom you have an epic sounding car that will do many pops and bangs and has some pretty good power
on my 97 chevy i just took the cats off and put exhaust cut outs on so its like open headers the pop and bangs are pretty big and loud for no tuning what so ever (i also shoot flames too lol)but i guess its not for everyone considering most states and countrys have emission test unlike here in florida where there is nothing
Consider the immense pollution you breath in and make others breathe in.
But then again you guys swim around in nuclear waste in Florida......
I love your proprod.. I prefer broomsticks, but 2x4's work..
Broom stick is the lightweight version
If pops and bangs can damage the catalytic converter, how come new CLA45's pops and bangs all the time without voiding warranty?
Can I call you Pop Pop now?
Mine keeps on making crackles and pops and ruining my mufflers.
How do I make it stop Yugoslavia?
I got a bit of a man crush bahahaha. Love these videos..
My ktm 525 pops and rumbles and flames come out of the exhaust even when im decelerating under load but the guy who had it before me did a lot of engine upgrades to the bike. It actually kinda worries me because im not sure if its hurting the motor or not. It has a cdi based ignition so idk what i can do besides jetting it to solve it
Who cares about an old engine. What about your neighbours having to listen to this shit.
How likely is it that this would cause damage to a turbochargers turbine wheel? Of course there are differences with turbos like material, mainly ceramic vs. steel turbine I suppose.
It’s technically anti lag if you have a turbo.
very late to comment but would this work on a Ford Focus sedan 2014
My Subaru non turbo is making pops and bangs , what could be the cause
My 2.0 16v Peugeot engine does that on stock ecu.
All you need to do is warm it up and do some spirited driving
So does my 1.6 mitsubishi, muffler just needed to fall off first so you could hear it🙃
brale sta je sa tom toyotom hoce li se to praviti ili ces je prodavati??
My car to pop when I let off the petrol but that was because the exhaust had a hole in it by the manifold, 😂😂
“That’s the third muffler this month”
I was exposed to pops and bang because of Initial D and that Evo III.
Misfiring sistum!!!
Bang bang bang bang!!!
But yea it also damages the turbine side of the turbo and shorten the lifespan of the turbocharger. Rally cars will run some sort of anti lag to keep the turbo in boost but at the cost of the shorter lifespan of the turbo but irrelevent since they will rebuild the engine after finishing a whole stage.
Bosno moja jabuko u cvetu :) .... lepo ti to radis ;)
Vidim ja da si ti nas covjek sta mislis bili mogao postici to na monopointu prekidajuci struju na svjecicama? Jer kod mene kad prekinem struju na kljucu ugasi se pumpa i dizna ne brizga gorivo tako da kad bih ugradio taster koji ce prekinuti struju na svjecicama kad pritisnem taster imao bih idalje struju na pumpi i dizni al bih svjecice ugasio
Are you running a batch fire injection system?
nevermind. your just control ignition. (jumped the gun)
i had a carburated bike when i was in highschool that pops and bangs with throttle is closed. I thought it was broken or something and was embarassed :D
Run a full straight pipe no cat no resonator no muffler trust me u won’t be disappointed
Mogu li ovo uraditi bez prčkanja po ECU, recimo samo spojiti na prekidač kojim bi prekidao iskru? Radi se o civicu 1999 d16z2? Pozdrav iz Vareša.
A sta bi postiglo prekidanje iskre?
@@d4a pa ubrizgavanje nezapaljene smjese u auspuh, što bi sljedeća postignuta iskra zapalila i napravila pucanje
Ali ne traje iskra ni blizu dovoljno dugo da bi takvo nesto funkcionisalo. Pored toga na EFI se mora isključiti fuel cut off kad se pusti gas. Uglavnom bez mogućnosti izmjene parametara unutar ECU-a ovo se ne može postići.
A ti bi ustvari da jednom iskra bude pa onda ne bude pa sve tako? Ni to ne moze jer nije poenta da se iskra desi ili ne poenta je da se desi kasnije a da gorivo nastavi dolaziti. Preskakanjem jedne iskre se opet nista ne postiže. To gorivo nezapaljeno nece stajati u auspuhu i čekati sljedeću iskru. Plus taj višak goriva kad iskre ne bude samo sapire cilindre i razrjedjuje ulje. Dakle iskra mora kasniti i opaliti kad se izduvni ventil otvori a gorivo nastavi dolaziti. Pored toga uvezivanje tog prekidača bi bilo komplikovano i moralo bi se povezati ne samo sa sistemom paljenja vec i sistemom papuče gasa.
@@d4a ma gledao sam neke ljude spoje prekidač i relej na bobinu( koju ja nemam) i onda valjda to prekida iskru
Bato šta treba da uradim kako bi dobio pops and bangs na bmw 320i M52 motor? Hvala.
Done that by using 1 short spark plug in a long plug setting
I wonder why you're not using an AEM ECU
It would be a bit of a shame to waste the potential of AEMs ECUs on an ignition only setup. But my upcoming turbo build will definitely be running an AEM ECU.
@@d4a makes sense. And you mean the 4A-FE, right? I'm looking forward to it. 👍
simple easy mods can be done on stock ecu if you take time
Yup, the 4afe
in a standalone ecu the fuel map does not control decel cut, look for a decel cut or overrun setting.
Some more primitive one's do, or less user friendly to beginner tuners etc. They will not offer decel tuning through a built in feature, but you can tune decel directly on the fuel map yourself.
Dicktator management is an example of a aftermarket aftermarket ecu that requires fuel map tuning for decel. Timing can be a bit tricky though.
I have a mixed relationship with exhaust pops, turbo futututu and other 'noises of performance'.
It sounds absolutely amazing in a group N rallye car drifting by, but in a otherwise stock 1.4l eco-box it sounds kinda embarrassing.
I can't say I don't agree, pops and bangs are also pointless on naturally aspirated engines. But I think it's a fun little experiment that also helps us understand engines and the combustion process a bit better.
@@d4a it is a good experiment yes, but it is ricery. But complaining about aesthetics on cars and saying slow thinss can't look fast is kinda stupid when some 80s sports cars at times are slower then a goddamn prius. That thing has a combined hp of 150hp
is it bad for you engine?
Pops and bangs...just as intelligent as newbie motorcyclist that pin the throttle wide open just to hear the engine bounce off the rev limiter.
Question is Why?
Nice mr2
What car is this?
Wait a minute - you WANT your exhaust to pop and bang?!
Yeah, like little children. They don't give a damn about the peace of the community, just their fun is all that matters.
Pops and bangs are imo one of the dumbest trend in the last 10 years.. it seems like every turbocharged car is tuned to deliver that annoyance nowadays. I truly don't get how can a driver not get annoyed after more than a few minutes of that nonesense..
Now that I know it slowly ruins engine internals, that "feature" seem even more stupid 😅
Shut up old you old men
Just install an M80 Muffler. It will pop and will not loose power or hurt the engine
my 1983 2.3 Capri makes this if I tank cheap fuel (cheap and all others - except Shell, works best. no probs)
if i want to do this over 4000 i set 0 only to 4000 and upper?
Yup, if it's fuel injected you will likely need to alter the map / disable decel cut etc.
@@d4a thanks
In my car with somewhat of an EFI error, if you downshift in a downhill without rev matching (just let the clutch out) it'll pop forever. Litteraly. It only stops if you give it gas back or eventually come to a stop after the downhill.
This is gross very early on, very annoying. You're just driving and pop pop
Now do it to a diesel
DSG farts. What about the cathalytic converter then?
bosnian table? ti si bosanac??
I swear I recognise this guy from another channel but I just can’t put my finger on it...
Nope, never been on any other channel except my own :)
driving 4 answers your face and voice is just so familiar!
Isn't retarding ignition to achieve pops by overlapping open exhaust valves with ignition very bad for exhaust valves. Having high flow of very hot oxidative gasses (partially burned mixture) eats away the valves and valve seats. I always thought the correct way in ECU controlled cars is to cut the spark and leave some fuel to be pushed into exhaust where it is ignited by hot exhaust or occasional spark event. In the carbureted cars it is different because at high RPM and closed throttle the engine creates a lot of vacuum and sucks too much fuel through the pilot jet nozzle which than burns in exhaust.
How about we don't mess with cars that don't actually have a reason to do this and not terrorize literally 95% of the world that already thinks you're annoying. Guess what, the people in the neighborhoods you run through hate you.
Keep in mind I'm referring to idiots that run a stock beater with bolt on pre-blued exhaust and pod filter next to their firewalls that couldn't outrun a prius on a good day. But I may also make an exception for the 15 year old base model mustangs that claims they can take on the world.
And as a sport bike rider, no, your shiny new 0-60 in 4.0 second anything can't beat a 600+cc...
Why not do a section of the Toyota engine that is most used in the world. the 5SFE and the 3SFE. Toyota sold millions of these engines all over the world. But never, no one has done a segment regarding the performance potential of these engines. Yes, we know, the 3SGTE opaque the 5SFE and the 3SFE. But how many MORE are one the street right now?
