Nice work. Going to sell some? Be good as a put-on & take-off as a quickchange when needed.

Side note: I heard a lecture once from some engineers at the highway dept. They were trying to quiet the road noise from a new highway. One thing that struck me informative: the exhaust pipes do act like a musical instrument in a way. The direction you point the tip of the exhaust is just like pointing the mouth of a trumpet.

The ATV guys are really trying to get a "silencer" for their woodsie stealth.
Popular one is the KOLPIN exhaust.
Looks like it may work similar to forklift after-muffler.
