RPM Polaris RMK AXYS 850 & 9R TITANIUM Snowmobile Race Weight Silencer AXYS 850 2019-2026

Maximize chassis weight savings and sharpen throttle response across your Polaris lineup with RPM’s Titanium Race Weight Performance Muffler! Engineered specifically for mountain riders, drag racers, and backcountry powder hounds seeking ultimate performance, this ultra-lightweight titanium race exhaust sheds an astounding 13+ lbs off the front chassis while unlocking an immediate +3 horsepower gain and razor-sharp throttle response across the powerband.

Constructed from premium, high-grade titanium with a compact 4" diameter muffler body, the unit weighs in at a featherlight 3.5 lbs (3.0 lb muffler assembly) compared to the bulky factory silencer. It connects directly to the stock OEM expansion chamber using factory spring locations with zero body cutting or machine modifications required. It delivers an aggressive, high-revving 2-stroke 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 instant power delivery are top priorities.

Installation is 100% bolt-on with step-by-step instructions provided for a fast, hassle-free setup with no clutching or ECU tuning required!
