Rattle

[SFfirebird]

I thought my exhaust was rattling because when i go over bumps it sounds liek that was rattling, so i took it down to the shop and they said they fixed it but they also said that my car was busted up inside. would that make the rattle that i am hearing..its a noticable rattle, and im starting to get pissed :mad:

if you have a dual exhaust system, sometimes the right side pipe will bang against a piece of metal (or fiberglass?) down there. If its just touching it it will rattle with the rumble of the muffler and the movement of the car. Also check to see if the metal guard over the catalytic converter is not loose, cuz this might be your rattle as well.
