I've had two different ones on my Honda. Can't remember the names of either one... First one, I "think" was called a "Bentz"? Anyway... It was a pretty simple affair, clamped on, quieted it down some. Second one, I can't remember the name of at all, but I know that the company I bought it from, got bought out by Kolpin and that is who sells them now. A more complicated and expensive arrangement than the first one, and required welding, but it's WAY more quiet. You really can't hear the exhaust on my machine at all anymore, all you hear is the mechanical motor noise.
If I ever get a new machine, I'll get another one of these mufflers for it.
