SPEEDWERX L2 Competition Series Lightweight Muffler // Stainless Steel // 2022-2025 Polaris 850 Patriot Boost RMK / VR1

• Stainless Steel Construction
• 10.9 Pounds Lighter Than Stock
• CNC Machined Diffuser
• Anti-Bog Outlet 
• 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 L2 muffler saves 10.9 lbs. over stock on the Boost 850 too!

The L2 Series muffler is designed to be lighter and louder than our original lightweight muffler. 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.
