for those of you with the greddy evo (coupe) exhaust....have you guys heard any rattling noises like below 1,500rpm?

for some reason mine started making this noise recently....i dont remember hitting anything and it wasn't like this when i put it on....its been almost a year since i had it put on

the sound seems to come when i step on the gas and below 1,500rpm....so like first and second gear....in the morning on a cold start, it's more noticeable

anyone know what it could be?

 

Mine is hitting the undercarriage on the passenger side just after the muffler, usually when slowning down to almost a complete stop or hitting bump.

 

mmmm......i dont think mine is hitting anything... i crawled under the car and had my sister rev the engine....its a weird sound cuz it sounds like something is actually rattling inside the pipe itself....when i hold the driver side pipe the sound muffles and goes away.

some weird stuff....i hope its not anything bad. the sound is pretty loud.... goes away after driving a while though

 

you think someone maybe threw something inside it? or some rat crawled in there???? nasty!
