In 2006 the management team at Competition Werkes were looking for a true race inspired exhaust for their new display bike. There was nothing on the market that captured the feeling of a custom MotoGP exhaust. They had the equipment, personnel, and desire. So WerkesUSA was created. The brand has become known for its amazing exposed welds. Yes, they are hand welded! Stainless steel GP-style Slip-On Exhaust. Lighter than stock muffler. Greater flow for more horsepower. Tapered baffle (on models with one) for better performance and advanced tuning. Hand welded from straight section tubing. Made in the U.S.A.
