Yoshimura Releases Yamaha R7 AT2 Stainless Race Series Exhaust

CHINO, CA – May 6, 2023 – (Motor Sports NewsWire) – When it came to crafting a special race exhaust for the Yamaha R7, we 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 our airbox so the gains we publish are just the start of a powerful package.

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

Product Details:

• For closed course competition use only
• Full stainless steel construction
• Saves 9.6lbs from the stock OEM exhaust system
• Includes M18 lambda sensor bung at the tailpipe
• Works with stock bike, but designed for highly modified race-tuned engines

• Optional sound insert kit available for -4dB if required (INS-20-K)
