Referred to as ... Conical racing tail pipe. Dont know if its stainless or titanium. Its about a millimetre too big for the pipe but the clamp squeezes it nice and tight.
Dont tell everybody.
That is the price with the silencer bit attached. He had no probs selling me the tailpiece separately. It came in its own wee box so it must be available on its own. 60 quid.
I wish my bike was that clean! I got an end piece from Halfords - £9.99 Only down side of this mod is fording, you either need to refit the can or just keep the engine revving at full bore
