RPM 2022-2024 Polaris Patriot Boost 850 / VR1 Turbo Stainless Lightweight Sport Muffler

Polaris Patriot Boost 850 / VR1 Turbo Stainless Lightweight Sport Muffler

Drop chassis weight, sharpen throttle response, and unlock extra horsepower on your boosted Polaris with RPM’s Stainless Steel Lightweight Sport Muffler! Engineered specifically for the Polaris Patriot Boost platform across RMK mountain and VR1 trail setups, this high-flow sport muffler sheds a massive 8.5 lbs off the front chassis while delivering an additional +4 horsepower and crisp, instant throttle response across the powerband.

Constructed entirely from 100% TIG-welded 304 stainless steel, the RPM Sport Muffler weighs in at just 7.1 lbs and features an integrated snow guard sealing guard to prevent snow packing and keep fumes out of the belly pan. The exit tip features a heavy-duty dual-wall construction designed to handle severe trail impacts from hidden rocks, stumps, and dense timber. Despite the increased exhaust flow, the muffler delivers a deep, rich performance note that remains compliant—passing the SAE J-2567 stationary sound test at under 88 dB.

Installation is 100% bolt-on with no machine modifications or additional hardware required, and seamlessly retains the factory OEM EGT sensor fitting!
