Description
Description
This Straightline Performance lightweight muffler is built specifically for the Arctic Cat Catalyst 858 platform, combining an 8-pound weight savings with a quiet, trail-friendly exhaust tone. The deep, mellow note keeps things comfortable for long days on the snow without drawing unwanted attention.
The premium ceramic-coated finish reduces radiant heat and under-hood temperatures while resisting corrosion through harsh winter conditions. It bolts directly onto stock or modified machines with no clutching or fuel calibration changes required.
