How to make exhaust pop

[J-Key]

had a play with a 172 the other day and his car was popping it sounded qulaity...

any idea on how to get your car to do this??

Decat, lift off the throttle when cold.

 

[AliasOmega]

can do it on the bike, keep the throttle as it was, engine off 1-2secs, back on..

nice pop and away we go.

 

[mcoppen]

Mine flames on over run after some spirited driving. Looks so cool in the dark.

 

[fuel_slut]

Sports exhaust with decat, rev the blox off it and lift off.. pop pop pop.

 

[Ronnie R]

Put Coco pops in where you put the fuel....or if u want snap crackle and pop... welll your just greedy

 

[Ian_182]

I drive a derv and dont know what any of you are talking about...lol

 

[Reyes]

Throttle, high revs, tap throttle

 

[J-Key]

hmmm ok, i used to have a 205 gti and it used to pop with the flames.. it handled so good aswell

I miss that car....

 

[danclarke]

Buy a focus RS, i had a decat system on mine, im pretty sure Chris from here can vouch for how much it popped/flamed

 

[Reyes]

RS4 too, sounds beefy, but in ifle you can pop it. If you get bored, buy one

 

[Chris n nic]

lol yeah that was class...especially on the motorway just as you were passing a police car on the hard shoulder hehe

[NIN-172]

My old xr3i used to pop when coming off the throttle when it had a custom exhaust on it, sounded mint
I got it replaced with a Janspeed after a while & the popping stopped

Take a plug lead off

 

[Jamesstone]

De-cat FTW... pop pop bang pop bang pop pop lol

 

[Ian_182]

That valver made some good noises

 

[Hutchie]

fit decat, and sport exhaust and you get nice pops, if your after more pops loosen the clamp on that mushroom shaped join behind where cat goes (dont think all clio's have this join though, as long as there is a slight leak and i mean slight from cat area )

 

[Inferno]

My Orbisoud (with cat) will pop and bang just after starting it up, until it's off that dodgy low emission map. Nothing when it's on the normal map though

 

[wiley]

decat plus remap

wiley

 

[Fraserb]

my scooby popped and spat flames but my cup doesn't but it does return over twice as much mpg

 

[Eckascliovalver]

my old valver used to spit blue flames over a foot long when giving it beans and changing gears and in hi revs all it took was tapping the throttle was decated with a magnex cat back system! oh how i miss that little thing :dapprove:

cup is s**t :rasp:

 

[B16DOE]

Sports exhaust with decat, rev the blox off it and lift off.. pop pop pop.

lol ture tho

 

[DrifteR197]

my 197 pops and bangs nicely , my rx7 pops but dont flame (but then its not de-cat).
my mates s14 flames stupidly, looks really good imo
oh and for any of you that think you've seen flaming, you havent till you've seen this, take a look bloody awsome

[Henry]

the pops/bangs/flames are caused by unburnt fuel passing through the engine and igniting in the hot exhaust.

you'd need to de-cat as part of the cat's job is to deal with unburnt fuel, and then you'd likely just need to get your exhaust hot and 'hope' the engine's passing unburnt fuel. exhausts on turbo charged cars tend to run much hotter than those on N/A cars

 

[Gary-Lew]

Most if not all 1*2s will pop from cold until closed loop control starts , just by prodding the acc on and off on the over run , Sounds pathetic

 

[Limca]

first you gotta let it snap, crackle, then it will pop

 

[clio_luke]

my milltek (with cat) pops when cold.
not half as much as when it was decatted. it was easy to make it pop then, and bang. lol

 

[seb]

when i was at the ring my standard 182 did quite a few pops when lifting off. sounds cool .

 

[cupholder]

stick it in 3rd at 120 mph that will make it pop

 

[maynard]

what are these decats like? many benefits? i want mine to pop!

 

[Kneel]

197 pops standard lol. S13 flames
decat, aftermarket exhaust = pops, bangs and occasional flames
