RPM Arctic Cat 858 Catalyst Titanium Chambered Q-Muffler

If you're looking to gain 4HP, cut 17 Lbs., and keep your sled sounding as close to stock as possible, the RPM Q-Series Chambered Muffler is your golden ticket. The RPM Q-Muf is a high performing, free-flowing, mechanically chambered QUIET muffler. Designed with a series of pass-through baffles and chambers, it effectively deadens sound without restricting airflow—so you won’t lose any power, and you'll even notice improved throttle response. At WOT the muffler’s design loads the chambers with exhaust flow, allowing excess CFM to overflow into the pass-through chambers, enabling freer flow when it's needed most. When the throttle is closed and exhaust flow is reduced, gases are redirected through the baffles and chambers for a deep, quiet tone.  Our uniquely designed oval domed top and bottom muffler body's eliminate any hot spots or fume dead spots providing a smooth free flowing path of exhaust gasses. The mufflers internals are fully welded to provide absolute most durable construction. All of our chambered snowmobile mufflers are backed by a 3 year manufactures warranty.
