This Straightline Performance Ultra-Light Muffler is constructed entirely from polished stainless steel and weighs just 5.3 pounds, saving 13 pounds compared to the factory exhaust. Built for the Arctic Cat Catalyst 858 chassis, it bolts on directly without fuel calibration changes and fits stock or modified machines.

The deep, aggressive tone sharpens the riding experience, while the polished stainless finish resists corrosion season after season.
