If you were to ask this question 3 years ago you would be getting a thread full of the BIG THREE. "PAZZO, CRG, or ASV" But with the quality of the knock-offs increasing so much you could pretty much go with whom ever you wanted. Me personally I still like Pazzo's and ASV's the best. Pazzo's because they come in so many color patterns and ASV's because they look HOT and their break away design is titts.
Hope this helps. What exhaust did you end up getting?
YES, I KNOW YOUR BIKE IS FAST............ BUT IS IT FAST WITH YOU ON IT!!!!
