well, actaully its been doing this since the day i got it. but its never really bothered me that much, especially cus all my friends thought it was cool. haha but anyway, when i let off the gas, and ESPECIALLY when i rev just sitting there...once i let off the gas and the engine's rpm's go down i get this kinda of "backfire" sound. its like VVVRRRRRRRRRRROOOMMMMmmpoppapoppmmmmpoppopmmmmmmmmmm

haha if u guess get that. It came with an aftermarket universal Naxos muffler on it, welded right to the pipe and it fits and all (well i haven't really inspected for leaks). I just put a custom CAI on it, with a filter going to a 3" civic intake and then to the maf and air temp sensor then to a pvc bend to the throttle body. i haven't even driven it with this on, just did it today. ive only revved..and it like amplifies the backfireing as well as eveything else.

just curious what u guys think..any similar experiences?

I could be backpressure..not backfireing. My freind had a Trans Am with his own custom catback system.. it had backpressure like crazy... The only thing i have heard about that is if its doing it your loseing HP... so ya might wanna rethink that exhast system.

you know... I had my car over a pit the other day when i was changeing the oil, and wouldn't u know... It already seems to have a custom-made catback on it! im sure its at least 2" but i dunno if its 2 1/4". Its not stainless or anything pretty, just custom bent pipe. but man id hate to hear it if it had stock pipe!

Mine does the same thing but sounds cool so I never worried.

I'll just end up doing a 2 inch pipe all the way back when I eventually get the 4-1 header from sharkracing and a performance cat.
