Dave's Muffler

My friend Dave has his bike over at the shop and has been doing some work on it. He wanted to do something diffrent with the exhaust so this is what we came up with. It seems to work really well to clean up the exhaust note. I like the look with the side panels on since its all hidden. bellow is a little vid of the bike with the header open and then with our muffler installed. Let me know what you guys think?
