Full Velocity Muffler // Polaris AXYS 800 H.O.

The Full Velocity Muffler delivers a stealthy, stock-like sound at low speeds that transitions into an aggressive bark at wide-open throttle. Engineered with a specialized thermal barrier, it drastically reduces under-hood heat while shedding 7 lbs of factory weight. Extensively tested to ensure precise back pressure, it guarantees enhanced throttle response and a 1-2 HP gain. Note: 2016+ models with electric start require minor trimming of the factory battery box for clearance, or the use of an aftermarket battery box. New exhaust springs (1.8" or 2.5") are highly recommended for installation.
