The eagerly awaited Yamaha R9 has arrived, and Yoshimura has crafted an AT2 Speed Series system that delivers remarkable results. By employing our AT2 muffler and ISC technology, we've enhanced the Yamaha R9's performance. The AT2 Speed Series offers a weight reduction of 4.5 lbs, providing a notable advantage. With this system, you can anticipate increased horsepower and torque across the entire power spectrum. Specifically, you may experience up to a 3.37% HP gain at 10,000 RPM and a 4.1% torque increase at 8,300 RPM, giving the R9 extended capabilities. Our Integrated Sonic Chamber enables us to amplify power beyond the stock unit, providing the R9 with an extra growl while maintaining 49 state compliance. Yoshimura's renowned aesthetics and sound quality are unmatched. A stunning Works Finish, from the headers to the tailpipe, offers a striking yet durable appearance, complemented by a custom carbon fiber heel guard. If you're familiar with the AT2 and CP3 engine platform, you'll appreciate the unique exhaust note emanating from the faceted end cap. Additionally, we offer an AB Bracket kit option if you choose to remove the passenger pegs. Yoshimura's Speed Series AT2 is proudly designed, developed, and manufactured in Chino, California.
