Yoshimura Race AT2 Yamaha YZF-R9 (2025) Stainless Full Exhaust System

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

Utilizing our AT2 muffler we've been able give the Yamaha R9 the legs it needs to perform. Removing 5.3 lbs pounds of weight is huge advantage with our AT2 Speed Series.

Performance on with AT2 Race Series system provide more horsepower and torque throughout the entire power spectrum. In fact you can expect up to 4.68% HP gain @10,000 RPM and a 3.14% torque increase @7,100 RPM. Now the R9 has longer legs!

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!

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

New Yoshimura Works Finish takes on a unique coloring after it goes through a heat cycle on the motorcycle that looks much like those titanium works components our factory racers use.
