Two Brothers Racing has the sport bike performance parts that are gonna help you hold it pinned over even the most rutted tracks. At TBR, our premium exhaust systems for Yamaha bikes outclass even our closest competitors. Stock exhausts are ugly, heavy, and rob you of valuable horsepower. Upgrade to a premium slip-on option for added strength and style or a full system replacement for optimal power across the entire rev range. We carry kits for Yamaha WR250s and WR450s, as well as YZ250s and YZ450s. And on Yamaha motocross bikes, all of our performance aftermarket exhaust systems feature our patented V.A.L.E. mounting system, which requires no welding and no springs.

For a detailed explanation of each type of exhaust system and canister available, please refer to the exhaust systems page.
