This Straightline Performance muffler is a direct bolt-on replacement for the Arctic Cat Catalyst 600, including M 600, Riot 600, and ZR 600 models from 2024 through 2027. It cuts 8 pounds from the sled, which makes the machine feel lighter and more responsive on the trail, and its ceramic-coated finish lowers under-hood temperatures while resisting corrosion.

The quiet version keeps the exhaust note deep and mellow without excessive noise, so it stays trail-friendly and legal-friendly for most riding environments. Installation needs no clutching or fuel calibration changes, and the kit includes the muffler and instructions.
