ever since i got my wheels put on there has been this wierd raddling noise underneath my car. It rarely happens while driving but when at a stop especially while in park, the thing raddles like hell!! I took it to like 3 shops and they all pointed out the muffler. I bought the magnaflow muffler and the raddling still is present! It seems to be right under the dash area (underneath of course). Anyone ever experienced this before?

 

Could the i-pipe be hitting the floor board?

 

hmm dunno, i'll check into that thanks

 

like the above said,it could be the I pipe,or Y pipe of you have headers. Could even be a collector of a longtube if it is a header.

 

my car is completely stock as of right now. I forgot to mention it.

97 non ws6 i asked a car shop mechanic and he looked, but didn't think that was it. (broken catalytic pieces)

 

93 or 94 car, could be a broken up catalytic converter piece rattling around

 

ok, sorry to tell u guys earlier but i ended up just replacing my whole muffler and tips, magn. pro series. lol sounds nice too, but the problem was.. the floorboard. some1 gave that suggestion and thanks for knowing your stuff. I wanted a better sound anyway so i don't regret it. TY all for input.
