SLEEPER PRO SLIP ON EXHAUST
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."
304 Stainless steel construction
The two-piece design of the Sleeper Pro is a streamlined update over the origianl three-piece sleeper design prior to 2016. The Sleeper Pro body is formed from 18 gauge stainless steel and finished to match the factory headers of your bike. The forming process, superior to a rolled cone, creates a continous radius throughout the exhaust body. Minimal seams, maximum strength. This is the proper 1960s Triumph exhaust.
No Repacking Required
The Sleeper Pro body encloses the louvre core mechanical baffle system. Each louvre is manufactured from a solid tube and pierced using our proprietary louvering tool. The body and baffle are then welded together at two points, full integrating the baffle and increasing the structural rigidity of the muffler.
Rubber Mounted Bracketry
Reduced Engine Vibration
Entirely redesigned mounting bracketry designed to be rubber mounted. This isolates engine vibration transfer to the rider for a better ride as well as reducing wear and tear on the bracket and exhaust body.
