SPEEDWERX Lightweight Muffler // Ceramic Coated // 2022-2025 Polaris 850 Patriot Boost RMK / VR1 / Assault

Speedwerx Lightweight Ceramic Coated Muffler for Polaris 850 Patriot Boost RMK / VR1 / Assault

Our Lightweight Muffler cuts 8 pounds from the Polaris Boost 850 while maintaining a trail-friendly sound level!

• Mild Steel Construction with Bright Silver Ceramic Coated Finish
• 8 Pounds Lighter Than Stock
• CNC Machined Diffuser
• Anti-Bog Outlet 
• Baffled Design is Quieter than Straight-Through Mufflers
• Allows Access to Chain Tensioner Bolt without Removing Muffler

Our Boost mufflers have a CNC machined diffuser which gives you a precision fit and finish as the exhaust leaves the turbo outlet. These mufflers feature our new ANTI-BOG deep snow technology which helps prevent bogging in deep snow conditions, this design allows the exhaust to escape the exhaust outlet when the bottom of the outlet is capped off or covered in deep snow conditions. Our mufflers show a small power gain with the stock ECU programming and improved throttle response as well. The Lightweight muffler saves 8 lbs. over stock on the Boost 850 too!

Our Standard Lightweight Mufflers are designed to reduce weight while keeping sound levels as low as possible. Our mufflers have more bark than stock units but we try not to make them too obnoxious. In other words, they won’t blow you off of your seat. We always have performance on our minds and our mufflers will either perform the same or better than the stock muffler. They utilize the stock outlet location and require no chassis modifications for installation.
