Drop maximum chassis weight, sharpen throttle response, and unleash extra horsepower on your boosted Polaris with RPM’s Titanium Lightweight Sport Muffler! Engineered specifically for the Polaris Patriot Boost platform across RMK mountain and VR1 trail setups, this ultra-lightweight high-flow muffler sheds an incredible 11.4 lbs off the front chassis while delivering an additional +4 horsepower and razor-sharp, instant throttle response across the powerband.
Constructed entirely from premium, 100% TIG-welded CP1 Titanium, this muffler weighs in at a featherlight 4.1 lbs total. It features an integrated Snow Guard Sealing Guard—a reinforced bottom plate that seals firmly against the belly pan to provide structural rigidity while blocking deep snow and exhaust fumes from entering the engine bay. The exit tip features a heavy-duty dual-wall titanium construction built to withstand severe impacts from hidden rocks, stumps, and dense timber. Despite the substantial increase in exhaust flow, the muffler produces a deep, rich mountain tone 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 extra brackets required, and seamlessly retains the factory OEM EGT sensor fitting!
