Graves Motorsports WORKS Exhaust System Yamaha R9 2025-2026

Graves Motorsports WORKS Exhaust System Yamaha R9

The Graves Motorsports WORKS Exhaust System for the Yamaha R9 represents the pinnacle of Graves performance exhaust development. Constructed entirely from premium-grade titanium and finished with a carbon fiber silencer, this full system was engineered without compromise to deliver maximum performance, reduced weight, and race-proven durability. Developed using technology refined through 31 AMA Professional National Championships, the WORKS system brings factory-level engineering directly to your Yamaha R9.

Every aspect of the system has been optimized for performance, from primary tube diameters and lengths to silencer core dimensions and collector design. When paired with Graves' exclusive FTECU flash tune, the system delivers gains of more than 8 horsepower through the midrange and over 13 horsepower at peak output while also eliminating ECU error codes commonly associated with performance exhaust installations.

Manufactured from the same 1.0mm thick high-heat titanium used in Graves Superbike competition exhausts, the WORKS system is designed to withstand temperatures up to 800°C (1472°F) while maintaining exceptional strength and oxidation resistance. Premium details including precision TIG welding, titanium spring tabs, aircraft-grade stainless rivets, titanium silencer bands, and a carbon fiber hanger complete a system built for riders who demand the highest level of performance and craftsmanship.
