I ended up buying a few used parts for $45. The silencer as it turns out is a Kawasaki YZ250 Pro Circuit already with the pipe modded to fit on a blaster. Looking at a side by side of the Bills pipe I have I may need to relocate a bracket but I bet it floes better than a stock one. Anyhow, everything in the pics below cost me $45 and I will be picking up a set of sand shark paddles for another $20 on Wednesday. Can't beat those deals.
