When it came to crafting a special race exhaust for the Yamaha R7, Yoshimura pulled out all the stops. Modeled after the titanium version, this Works Finish stainless system is the perfect balance between performance and value. Created with premium alloy material, then prototype after prototype until we reached the final test system. On a stock engine with no mods and 91 octane pump fuel, this new system creates +5.7% max HP and +2.7% max torque. This system is designed to create even more performance with motor work and Yoshimura airbox so the gains we publish are just the start of a powerful package.
