Exhaust rattle: Post #2286-2289: The rattle in your exhaust is probably the inner pipe rattling against the outer pipe. I took mine to a custom exhaust shop and he cut in half right near the start of the larger diameter section and determined it was a two pipe design which is common he said. He drilled a hole underneath the heat shield and welded the two pipes together. That "fix" broke right away on me. If yours is like mine the rattle goes away when you press your foot down on the heat shield. I removed my heat shield and drilled two holes through the outer pipe. I then took two self threading machine screws and tightened them down "cinching" the inner pipe so it cant rattle anymore. The screws can't be seen because they are under the heat shield. Been a few months and she is still rattle free!!! My friends told me to let it rattle but it drove me CRAZY!!! Definitely glad I got rid of it.
