poppin` n` bangin`.

[trevtubby]

I`ve recently fitted a straight through exhaust system onto my car, and since then the car has been popping and banging a lot at around 2k rpm when I lift off, just when im cruising along.

I figured the car was overfuelling a lot and had the power FC remapped asap at WGT, but the car is STILL popping and banging a lot. Its actually a little bit embarassing, I bet people think the car is backfiring.

Does anybody else`s rex do this?...

I think everyones does mate

Its just the unburnt fuel in the exhaust. As you have straight through exhaust now there is nothing stopping the unburnt fuel from getting through

Just out of interest, my standard ecu rebuilt 12k ago, does not pop or bang at all! but i think they are known for it,

mine does it regularly when lifting off - adds to the appeal of an RX :Giggle

[G@NDY]

Why doesnt mine do it:(

[MissRX7]

Yep mine sure does..:3gears-rh

[Grizzly]

I\'ve noticed mine does it more with a decat fitted. It did pop a bit with the Cat on but it was more toned down than the noise it makes now.

Dam it - mine hardly ever does it! :spank

Mine does it when it\'s cold all the time on over run!! and now and again when I change gear at about 3K

mine does it too, if i ease off the loud pedal gently it doesnt seem to do it as much.

check your battery contacts too, it pops less since i sorted out a slightly loose terminal...

rotors have to run pretty rich, so your never going to fully eliminate the problem.

ok thanks for the reply`s guys, it never banged at all until I fitted the exhaust.
Its quite appealing but sometimes it can get a tad annoying.

mine does about 2-3k when lifting off i love it! scared the sh**e out of me the first time i was driving i thought some thing had dropped off:)

[PIPFC]

mine does it around 2-3k and when i push it hard -to around 7k- it sometimes spits flames:Laugh

gotta love decatted exhaust\'s:Thumbs-up

[Bobbit]

I have to say i love it! As it has been said before it just adds to the appeal of these cars, it\'s more frequent on mine in the cold, but it usually calms down after 10 mins or so, unless driving spiritidly(sp?) and then she pops and bangs like a bad drummer, get flames too! WOO HOO!

I get lots of popping and banging, mildly when the cars cold and loud when everythings warmed up and I\'m giving it some...and I have a Knight Sports high-flow cat fitted :Laugh
