Yoshimura's AT2 slip-on for the 2011-on GSX-R600 and GSX-R750: a faceted rear cap inside a matte carbon fiber end cap, with a matching heel guard. It weighs 4.6 lb against the 5.3 lb stock muffler and adds horsepower, torque and the Yoshimura sound. If you need it quieter, the INS-27-K low-volume insert is sold separately. Made in Chino, California.
