Please specify which model when ordering. A replica of the originals, but these are made from a heavier guage steel than most of the other manufactured pipes you can purchase. This means that they last longer, and are less susceptible to light damage and colouring. These exhausts are made here in Britain, as much as possible the welds are levelled and not visible to the naked eye after chroming. The silencers are fitted with baffles where required, creating a superb sound that you would expect from motorcycles of this ilk.
