Re: "soda can* exhaust
There was a "fad" a few years back in the R/C world of the mousse can exhaust. It worked well on the 2stroke 50cc+ gas engines and was fairly quiet considering. I made something similar for my wifes Buell Blast from one of the aluminum beer bottles. It worked well and sounded good. Looked pretty cool too. Simply attatched it at the threaded end and drilled the proper amount/size of holes in the base end(read experimentation).She cleaned it off on an off road excursion in a turn. That was the end of her riding career and the Blast.
