Make sure everthing is tight and check to see if you need new hangers and rubber for the exhaust.

is it rattleling near the engine? if your useing the stock exhaust or headers that use the stock heat riser piece, i had a rattle once and it turned out to be the linkage on the heat riser. removed the linkage, problem was solved.
just a thought.
