The DMC Quiet system is the perfect choice for the track or the trail. Designed to improve the spread of horsepower, torque and acceleration while keeping sound down to strict USFS sound requirements. Features include a completely re-packable extruded alloy silencer with premium packing material, T-304 Stainless steel mid-pipe, AMA/FIM approved end-cap, removable U.S. Forestry approved spark arrestor and DMC S.O.S. (Save Our Sport) quiet insert. The Pro Quiet pipes maximize performance as a full system, but can also be purchased individually as a slip-on muffler or head-pipe. Purpose built to conform to all off road noise regulated applications, our test results show an output less than 96 decibels.
