So I have narrowed down the exhaust that I want to either the Vance and Hines Big Shots Staggered Black or the black Thunderheader. Any opinions or performance stats to help me with my decision would be appreciated. I did order the Vance and Hines Duke air cleaner and the TFI for the bike. Just waiting to get home to apply it. May just go ahead and order the exhaust and send it all back to the dealer to be installed before I get there. That way I can try to enjoy the bike a little before it becomes a garage ornament for the winter.
