Two Brothers Racing Mufflers

Two Brothers S1R Black Series Race Slip-On Mufflers

Two Brothers S1R Black Series Race slip-on mufflers have a sound of pure power in their newly conceived look. It's not just a pretty face; the improved technology increases all-around performance. These competition mufflers are totally blacked-out at each end. They feature anodized black trim and a black/gray TBR logo. You still get all the benefits of the original S1R muffler—like a stamped spring-fit inlet, aluminum CNC-machined outlet, and a lightweight PTFE-coated magnesium end cap. Two Brothers S1R Black Series Race slip-on mufflers are available in aerospace high-temp carbon fiber, high-temp stainless steel, or polished aluminum. Order the model (with preferred options) recommended for your bike application. Additional notes and features include: * Rubber-lined styled mount * Spiral-wound perforated core * USFS-approved removable screen-type spark arrestor * Accepts P-Series sound-reduction tips
