Mine does the same thing.....its more than likely something on the exhaust.....I know its my exhaust that's rattleing....to fix mine I'm going to losen up my exhaust claps throughtout the exhaust from midpipe back, shake it to losen it up thenjust tighten it back up

If you have a Magnaflow cat back it is probably the muffler busted loose inside.

Haha there you go I fixed it!

But I hope it's not my muffler....I knew I should have bought one of those mrb dual tip systems!

On the exhaust take a look at the very back hanger, there is a brace that goes across from the bumper to the frame and that back exhaust hanger usually rattles against that brace and causes a rattle, the exhaust will move forward and back causeing the rattle to come and go.
