Combine whisper-quiet trail manners with maximum 2-stroke power gains and ultra-lightweight titanium construction for your Polaris! The RPM N.A. Q-Muf is a high-performing, free-flowing, mechanically chambered quiet muffler engineered specifically for Naturally Aspirated (N.A.) Polaris 650, 850, and 9R Patriot engine platforms across AXYS and Matryx chassis models. Only slightly louder than factory sound levels at idle, it delivers massive gains in exhaust velocity, throttle responsiveness, and weight savings.
The secret to the Q-Muf's performance lies in its intelligent internal acoustic architecture. At low RPM and idle, exhaust gases flow through a series of precision pass-through baffles and mechanical chambers to deliver a deep, whisper-quiet sound signature. Under Wide-Open Throttle (WOT), exhaust flow loads the primary chambers and automatically overflows into pass-through channels—allowing exhaust gases to vent freely without power loss, restriction, or backpressure spikes.
Constructed entirely from 100% Titanium with fully welded internals, the Q-Muf weighs in at an astonishing 4.4 lbs total, shedding 11.4 lbs off the front chassis compared to the stock muffler. The uniquely designed oval-domed top and bottom muffler body eliminates thermal hot spots and dead zones, ensuring smooth exhaust scavenging. It features an integrated bottom titanium snow plate to block fumes and packed snow from entering the chassis tunnel when submerged in deep powder, as well as an ultra-tough dual-wall titanium exit tip built to withstand hard impacts from rocks and tree stumps.
