Drop maximum weight and sharpen throttle response across your entire Polaris lineup with RPM’s Stainless Steel Race Weight Performance Muffler! Engineered specifically for mountain riders, drag racers, and backcountry powder hounds seeking raw performance, this ultra-lightweight race exhaust sheds a massive 11.65 lbs off the front chassis while unlocking an immediate +3 horsepower gain and razor-sharp throttle response across the powerband.
Constructed from heavy-gauge, corrosion-resistant 304 stainless steel, this compact 4" diameter muffler body weighs in at just 5.0 lbs (compared to the bulky 16.65 lb factory silencer). It connects directly to the OEM expansion chamber using factory spring locations with zero body cutting or machine modifications required. It delivers an aggressive, high-output exhaust note that cuts through mountain air—making it ideal for open mountain terrain, closed-course racing, and backcountry riding where minimal nose weight and crisp power delivery are top priorities.
Installation is 100% bolt-on with step-by-step instructions provided for a fast, hassle-free setup!
