i know this topic has come up in the past, so i thought i would post a few pictures of what i did to quiet mine down a little. it also makes it U. S. forest approved.

Wow, I don't think I've ever seen a supertrapp on a 2 stroke before.

How much quieter would you say it is?

somewhere around 25 to 30 percent. It' still prety loud. The main thing i was after was a spark arrestor so i can ride at all the parks without any trouble.
