Yoshimura AT2 Race Stainless Full Exhaust System with Stainless Muffler | Works Finish | Closed-Course

The Yoshimura AT2 Race Stainless Full Exhaust System is a complete closed-course header-back exhaust built around a stainless steel header and stainless steel muffler, an all-new faceted matte carbon fiber end cap assembly, an application-specific carbon fiber heel guard, and Yoshimura's exclusive Works Finish.

AT2 stands for Alpha Taper 2, Yoshimura's current-generation Race Series canister. The Works Finish is what sets it apart visually: rather than a fixed coating, it develops its colour through the system's first heat cycles on the motorcycle, finishing close in appearance to the titanium works components on Yoshimura's factory race machines.

This is the all-stainless version of the AT2 full system — the same header, canister geometry and carbon end cap assembly as the carbon-sleeved version, with a stainless muffler body in place of carbon fiber. It is the more durable of the two options and the usual choice for a bike that sees regular track use rather than concours duty.
