Jim, most Harley dealers over here, [UK] are MOT centers and turn a blind eye [ear!] to straight through exhausts. That said, so does my Triumph dealer! Loud pipes have their place, and I think that you don't take the p*%$ in populated aeras they're ok, or get tugged by the fuzz. [pulled by the cops]

P.S. Anyone have a Thruxton Velocette I can photograph?
