Yoshimura AT2 Race Stainless Full Exhaust System | Suzuki Hayabusa 2022-2026 | Works Finish, Closed-Course

The Yoshimura AT2 Race Stainless Full Exhaust System is a complete closed-course header-back exhaust for the 2022-2026 Suzuki Hayabusa, featuring a stainless steel system in Yoshimura's exclusive Works Finish with an all-new faceted matte carbon fiber end cap and an application-specific carbon fiber heel guard, delivering a 4% peak horsepower gain while dropping system weight from 42.8 pounds to 14.3 pounds.

That weight figure is the headline. The third-generation Hayabusa's factory exhaust is enormous — nearly 43 pounds of catalyzed stainless — and the AT2 system removes more than 28 pounds from the heaviest part of the motorcycle, low and to the rear. On a bike whose only real dynamic weakness is mass, no other single modification comes close.

The AT2 canister is Yoshimura's current-generation Race Series profile, and this application gets the full treatment: the new faceted inner end cap assembly, matte carbon outer cap, and a heel guard shaped specifically for the Hayabusa's rider footpeg position rather than a generic shield. The entire system is built at Yoshimura R&D of America in Chino, California.

• Stainless steel construction in exclusive Yoshimura Works Finish
• All-new faceted matte carbon fiber end cap assembly
• Custom matte carbon fiber heel guard specific to the Hayabusa application

Fits the 2022-2026 Suzuki Hayabusa (GSX1300R) as a direct replacement for the complete stock exhaust system, and is the definitive weight-reduction and power upgrade for third-generation Hayabusa builds used in roll racing, drag racing and closed-course top-speed events.
