Straightline Performance Yamaha Mountain Max 800 Ultra Lightweight Stainless Steel Muffler

Full Polished Stainless Steel Construction

14 Pounds Lighter Than Stock

Race-Proven Performance. Built to Last.

The Straightline Performance Yamaha Mountain Max 800 Ultra Lightweight Stainless Steel Muffler is engineered for riders who demand exceptional durability, significant weight savings, and proven performance. Designed specifically for the Yamaha Mountain Max 800, this premium muffler combines lightweight construction with full polished stainless steel to deliver years of dependable service in the toughest riding conditions.

Manufactured entirely from premium polished stainless steel, this muffler features stainless steel construction from the inlet to the outlet, including the internal performance core. Every muffler is precision TIG welded to ensure exceptional strength while maintaining a lightweight design that removes approximately 14 pounds compared to the factory exhaust system.

Removing 14 pounds from one of the highest points on the snowmobile dramatically improves handling, maneuverability, sidehilling capability, and overall rider confidence. The lighter weight makes the sled feel more agile and responsive whether you’re climbing steep terrain or carving through deep powder.

The high-flow internal core improves exhaust efficiency, delivering quicker throttle response, stronger acceleration, and a deep, refined performance exhaust tone that complements the Yamaha 800 engine without being overly aggressive.

Every Straightline Performance Ultra Lightweight Muffler has been dyno tested and field proven to ensure outstanding performance and long-term reliability. Precision TIG-welded construction and premium stainless steel materials provide exceptional durability for years of aggressive riding.

Straightline Performance guarantees this muffler will never crack a weld or experience structural failure under normal riding conditions, giving riders complete confidence every time they head into the mountains.

Installation is quick and easy with a true direct bolt-on design that utilizes all factory mounting locations. No cutting, fabrication, fuel programming, or tuning is required.

If you’re looking for a premium lightweight stainless steel muffler that offers outstanding durability, exceptional craftsmanship, and proven performance, the Straightline Performance Yamaha Mountain Max 800 Ultra Lightweight Muffler is the perfect upgrade.

Noticeable power gain
Needed a fix for my sled and this did the trick. Sound is deep without being obnoxious. Bolt-on install, no tuning needed. Glad I made the switch.
