The Lightest Muffler in the Industry

True Carbon Fiber Construction. Premium Stainless Steel Internals.

Maximum Weight Savings with Lifetime Rebuildable Performance

The Straightline Performance Yamaha Mountain Max 800 Lightweight Carbon Fiber Muffler is the ultimate exhaust upgrade for riders looking to remove maximum weight while adding premium performance and race-inspired styling to their Yamaha Mountain Max. Designed specifically for the Yamaha Mountain Max 800, this muffler is one of the lightest performance mufflers available anywhere in the industry.

Constructed using a true carbon fiber outer body combined with fully polished stainless steel inlet, outlet, and internal components, this muffler delivers the ultimate combination of lightweight performance, exceptional durability, and premium craftsmanship.

Removing substantial weight from one of the highest points on the snowmobile dramatically improves handling, sidehilling, maneuverability, rider confidence, and overall sled responsiveness. Whether you’re climbing technical terrain or carving through deep powder, you’ll immediately notice how much lighter and more agile your Mountain Max feels.

Inside the muffler, a precision-engineered stainless steel performance core provides excellent exhaust flow for quicker throttle response, improved engine efficiency, and a deep, aggressive exhaust tone that perfectly complements the Yamaha 800 engine.

Every muffler is precision TIG welded and built to Straightline Performance’s exacting quality standards to ensure outstanding fit, finish, and long-term reliability.

Unlike disposable mufflers, the Straightline Performance Carbon Fiber Muffler is designed to provide a lifetime of service. Because it utilizes premium packing material inside the carbon fiber canister, periodic maintenance is recommended. Depending upon riding conditions, engine modifications, riding style, and accumulated mileage, the muffler packing may eventually require rebuilding.

This is completely normal for high-performance carbon fiber mufflers and is one of the reasons they remain the preferred choice for professional racers and serious riders. The muffler is fully rebuildable at any time, allowing it to provide years—even decades—of dependable performance while maintaining its lightweight advantage.

Installation is simple with a true bolt-on design that utilizes all factory mounting locations. No cutting, fabrication, or permanent modifications are required.

If you’re looking for the absolute lightest muffler available while maintaining premium quality, rebuildable longevity, and outstanding performance, the Straightline Performance Yamaha Mountain Max 800 Carbon Fiber Muffler is the ultimate choice.
