I've seen the videos for tab performance. I was hoping to find someone other than the manufactures videos of some aftermarket options.
S&S has a video out there for M8 Slip ons. In my opinion, they sound way better than the Tab.. And if you hold on for a bit, Fuel Moto is around the corner with their's. I've personally heard the Fuel Moto's on previous Gen bikes, and they rock.
Bought the street cannons because dealer scared the S#%t out of me about voiding my warranty, wish I could get that money back. Now have the RC slip ons, very happy.
here is a list of some of the slip ons i've found for the m8:
bassani
cobra
rc component
rinehart
2 bros
v&h
rush
s&s
most should be available in november
