Yoshimura AT2 Full System Exhaust - Stainless Steel - 13720AP520

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 they 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 the airbox so the published gains are just the start of a powerful package.

Losing 9.6 lbs from the stock system, the AT2 is ready to make your R7 move! The design of the AT2 tucks nicely under the lower cowling to keep it from harm's way as much as possible.
