When it came to crafting a special race exhaust for the Yamaha R7, Yoshimura pulled out all the stops. Created with premium alloy material then prototype after prototype until they reached the final test system. On a stock engine with no mods and 91 octane pump fuel, this new system creates +6.2% max HP and +2.7% max torque. This system is designed to create even more performance with motor work and our airbox so the gains published are just the start of a powerful package.
Loosing over 11 lbs. from the stock system, Yoshimura's AT2 is ready to make your R7 move! The design of the AT2 tucks nicely under the lower cowling to keep it away from harms way as much as possible.
