i have a triumph thruxton with TRIUMPH OFF ROAD SILENCER'S fitted,they are marked (NOT FOR ROAD USE) i like the sound it make's,after a visit from a couple last weekend & a couple walking past moaning about the noise,i've decided to put the OEM SILENCER'S back on it,with the factory re-map !!!!! i started the GTR last sunday with a scorpion end can with the BAFFLE IN & i over heard passer's by moaning,if this carrie's on i will call call the police,as far as i'm concerned as long as the scorpion is stamped & has the baffle in,they can't do anything about it.i only get the bike's out on the odd weekend,it's not like i'm starting them up & revving the ball's out of them.i think they ain't got anything better to do.
If your pipe is legal then I would just ignore them. :yes:
