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.
FITMENT NOTE - Due to collector configuration, Full System ground clearance is slightly reduced compared to stock system
