What tye of rattle? Metal to Metal? Metal to body?

Make sure the exhaust isnt touching the heat shield, cats are still good, and tips are not making contact with the bumper.

Also check the welds on the h-pipe. You'll just have to get under the car, and do some poking around.

It could be the infamous H-pipe exhaust jingle. An aftermarket x-pipe fixes it for good.

While you have the car up in the air checking, be sure to look at the cats. If the substrate is breaking up, it can make a lot of noise. Give each cat a good tap with a rubber mallet, you will hear the insides bouncing around if they are bad.

Make sure your Lic. plate is tight... I thought my exhaust was rattling and while washing the car found the Lic. plate was loose... thats a e-z fix...
