Comp 4 Full System Muffler
These closed-course race systems utilize the latest DMC technology to deliver big gains in acceleration, horsepower and torque throughout the entire power band while meeting AMA Sound Requirements. DMC has captured additional strength and critical weight savings (Low-CG muffler placement) by utilizing extruded alloy and T-304 Stainless Steel construction. The DMC Pro Comp pipes maximize performance as a full system, but can also be purchased individually as a slip-on muffler or head-pipe. The Muffler comes equipped with AMA/FIM approved end-cap and U.S. Forestry approved, removable screen spark arrestor. Silencer is easily re-packable in minutes. The perfect system for those serious about SX, MX or Off-Road racing!
