.. Honestly, I would just bring your car to your local exhaust shop and have them look at it.. Most places like midas will look at it for free.

i wasnt refering to glround clearance, im refering to the clearance b/w the y pipe and the floorboard o fthe car, if its a real tight fit id bet thats your noise maker!

if the clearance there is fine and it sounds to me the noise came after all this was installed id check the muffler, mabey a broken baffel inthere. had an ol set of flowmasters on one of my 3rd gens do that, that thing rattled its *** off and was annoying as hell
