Straightline Performance Arctic Cat Catalyst 600 Ultra-Light Muffler

This Straightline Performance Ultra-Light Muffler is a direct bolt-on replacement for the Arctic Cat Catalyst 600, built entirely from polished stainless steel and weighing just 5.3 pounds. That 5.3-pound figure represents a 13-pound weight savings over the factory exhaust, and because the weight comes off the rear of the sled, the machine becomes noticeably easier to handle in technical terrain, deep snow, and aggressive mountain riding.

The polished stainless steel construction resists corrosion and keeps its clean, high-end appearance season after season, while the muffler delivers a deep, aggressive tone under acceleration that stays comfortable during normal riding. It fits the Arctic Cat Catalyst 600, M 600 Catalyst, Riot 600 Catalyst, and ZR 600 Catalyst, works with both stock and modified machines, and requires no fuel calibration changes.
