This Straightline Performance mountain muffler pairs a genuine carbon fiber body with polished stainless steel inlet and outlet components, giving Catalyst 600 riders a direct bolt-on upgrade that resists corrosion in harsh snow conditions. The carbon fiber construction is built to handle heat while trimming weight from the sled, which translates to easier sidehilling and quicker response in technical terrain and deep snow.

It delivers a deep, aggressive tone under acceleration while staying comfortable during normal riding, and it installs without fuel calibration changes on stock or modified machines. Because carbon fiber mufflers are a serviceable component, periodic inspection and repacking keep sound quality and performance on point.
