British Customs Sleeper Pro Slip-On Exhaust - BC902-123-BR
The Sleeper Exhaust was originally designed in 2008, the peashooter design pays tribute to the 1960s and 70s factory Triumphs. The goal of the Sleeper was to increase the performance and improve the exhaust note while keeping close to the original Triumph aesthetic; more power with a toned down appearance, hence "Sleeper." In 2017 the Sleeper Exhaust was redesigned and released as the Sleeper Pro. 9 years of design, testing, and customer feedback was used to develop the Sleeper Pro. The look and the sound has not changed, but the internals have been completely redesigned for additional durability and weight savings.
