The Triumph Slip On Exhaust Named After the Hardest Road Race on Earth

Since 1907 the Isle of Man TT has closed 37 miles of public road on a small island in the Irish Sea, once a year. Stone walls at arm's length. A mountain section that has ended careers. The bikes that won there were never the quietest ones.

We named this exhaust after that race, not as a tribute but as a standard. The Two Stage Core runs two baffles at two different diameters to control flow in sequence, so mid range torque survives corners, rolling throttle, and city traffic. The Dimpled Baffle shapes a deep, classic note that brings out the natural voice of your engine. At 2.4 pounds per silencer against 8 to 10 pounds of stock muffler per side, the weight comes off the back of the bike where you feel it first.
