Graves Motorsports WORKS Exhaust System Yamaha R9

The Graves Motorsports WORKS Exhaust System for the Yamaha R9 stands as a benchmark in performance exhaust technology. Made entirely from premium-grade titanium with a carbon fiber silencer, it is engineered for maximum performance alongside reduced weight and proven durability. Drawing on insights gained from 31 AMA Professional National Championships, the WORKS system delivers factory-level engineering to the Yamaha R9. Every detail of the system is refined for optimized performance, from the primary tube dimensions to the silencer core and collector design. When combined with Graves' FTECU flash tune, it achieves gains exceeding 8 horsepower in the midrange and over 13 horsepower at peak output, while also resolving common ECU error codes encountered with performance exhaust setups. The system employs 1.0mm thick high-heat titanium, capable of enduring temperatures up to 800°C (1472°F) without sacrificing strength or oxidation resistance. Exceptional features include precision TIG welding, titanium spring tabs, aircraft-grade stainless rivets, titanium silencer bands, and a carbon fiber hanger, making it ideal for riders seeking top-tier performance and craftsmanship.
