RPM Polaris RMK & VR1 Patriot Boost Q-Muf Chambered Titanium Muffler

Patriot Boost850 Turbo Titanium Q-Muf

Combine whisper-quiet trail manners with full-throttle boost performance and ultra-lightweight titanium construction for your Patriot Boost! The RPM Q-Muf is a high-performing, free-flowing, mechanically chambered quiet muffler engineered specifically for Polaris Patriot Boost 850 snowmobiles. 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) and full boost, 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 3.8 lbs total. 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.

Performance Metrics & Weight Savings:

• Horsepower Gain: +3 to +4 HP Increase @ Full Boost

• Total System Weight: 3.8 lbs (Sheds massive weight off the front chassis)

• Material & Construction: Full Titanium Structure with Fully Welded Internals

• Sound Level Profile: Slightly louder than factory at idle; free-flowing and controlled under WOT

• Exit Tip Construction: Heavy-Duty Dual-Wall Titanium

• Warranty: Backed by RPM's 3-Year Manufacturer Warranty

• ECU Tuning Required: None (Direct drop-in and go)

Features:

• Smart Mechanical Chambered Design: Transitions seamlessly between whisper-quiet baffled idling and high-CFM free-flowing exhaust pathways under full boost.

• Sheds Massive Front-End Weight: Extremely lightweight 3.8 lb titanium build improves front-end agility, side-hilling control, and deep powder flotation.

• 3–4 HP Performance Increase: Maximizes exhaust gas velocity to improve power delivery and deliver instant throttle response.

• Integrated Bottom Snow Plate: Built-in titanium plate seals the belly pan to keep snow and exhaust fumes out of the tunnel when submerged in deep snow.

• Heavy-Duty Dual-Wall Titanium Tip: Protrudes further than competitor mufflers for clean exhaust deflection while shielding the outlet from rock and stump impacts.

• Oval Domed Muffler Body: Prevents thermal hot spots and exhaust fume dead zones for maximum gas velocity and longevity.

• Over-Built Mounting Brackets: Extra-duty reinforced titanium mounts prevent bracket fatigue and failure under severe mountain riding abuse.

• Drop-In Bolt-On Installation: Installs directly into original factory mount locations with zero body cutting or ECU re-flashing required.
