Yoshimura AT2 Stainless Full Exhaust 2025 Yamaha YZF-R9

Yoshimura AT2 Stainless Full Exhaust 2025+ Yamaha YZF-R9

The highly anticipated Yamaha R9 is finally here and Yoshimura has developed an AT2 Speed Series system with profound results.

Utilizing our AT2 muffler and our ISC technology we've been able give the Yamaha R9 the legs it needs to perform. Removing 4.5lbs pounds of weight is nice advantage that comes with our AT2 Speed Series.

Performance on with AT2 Speed Series system provide more horsepower and torque throughout the entire power spectrum. In fact you can expect up to 3.37% HP gain @10,000 RPM and a 4.1% torque increase @8,300 RPM. Now the R9 has longer legs!

Our Integrated Sonic Chamber allows us to boost power over the stock unit and gives the R9 extra bark all while keeping the new Speed Series full system 49 state friendly.

Aesthetics and sound are second to none when it comes to Yoshimura. A brilliant Works Finish from the headers to the tail pipe provides a look that is beautiful, yet durable. A custom carbon fiber heel guard finishes the look. If your familiar with the sound of the AT2 and the CP3 engine platform, you know the one of a kind exhaust note that emits from the faceted end cap is insane!

We also offer an AB Bracket kit option if you elect to remove the passenger pegs.

Yoshimura's Speed Series AT2 is proudly designed, developed and manufactured in Chino, California.
