I am a new owner of a 2000 5th gen. It came with a Staintune exhaust. The sound is really incredible, but I can see myself wishing it was a little quieter on long trips. Question is: Is there a silencer that can be added to turn it down a bit? I had a 6th gen with Leo Vince exhausts. At the end pipe coming out of the muffler was a smaller piece of silencer pipe held in place by a small screw, inserted from the bottom. Thoughts?
