Let’s face it, there is only one choice for the GSX-R1000 when it comes to the best exhausts and engine platform... Yoshimura.

Introducing our latest muffler design, AT2 for the bike that has won many superbike championships and has a special place in the heart of Yoshimura.

Our AT2 full system includes all the same features as our slip-on and delivers pure performance you would expect from Yoshimura. Peak horsepower is up 6.3% in all the right places and torque up 2.4% with 8.7 lbs. weight saving. Get ready to “Feel The Speed”.

*AT2 muffler shown is a prototype and not a production muffler.

Zoe D. ★★★★★

Swapped out the stock can this weekend and the AT2 fit the hangers perfectly without any wrestling. The stainless finish looks sharp and the sound is deep without being obnoxious on the street.

Andrew X. ★★★★★

The AT2 muffler is noticeably lighter than the stock can, and the stainless build feels rock solid. Bolted it on in the garage without any fitment headaches, and the sound is exactly what I wanted from a race series system.

Lily Q. ★★★★★

Had it on the track last weekend and the mid-range pull is noticeably stronger than stock. The stainless build quality is legit, and the AT2 muffler looks sharp without being obnoxious.
