under engine exhaust system.

[Rick G]

All this exhaust talk has me thinking about the style of exhaust system on the Buell, the new Kawasaki  Ninja 650, Yamaha R6 and a few others.
I think an under engine system  would work well, All I have to do is figure what to use for a muffler.

I have never  been a fan of sport bike  exhaust systems,  the first one I saw  looked like a dolled up version of a car muffler . No style and looking like an after thought. 
I have an idea on  how to go about it , I'll just have to keep my eyes open for a suitable muffle I can adapt. I may end up  fabing it my self.
