For slip on's I have heard great things about the FMF. For full systems, I am big on the Yoshimura RS-2. Dr D is another great pipe but I think it just adds bottom end power, not impressed with the over rev on top.

A simple search on the string "best AND exhaust AND 08" returned 202 threads, at least 30% of which were directly related to this same question.

yeah i we been googeling it in different formats but i wanted to see what comes up with TT riders...mate:busted:

That was 202 threads in this forum.
