Yoshimura's ALPHA slip-on with a carbon fiber sleeve for the Ninja 1000SX (2020 on, including the 1100SX). Yoshimura set it up for more pull at the top, measuring 4% more peak horsepower and 4.7% more peak torque, and tuned the note so it does not drone in your helmet on a long ride. It weighs 5.5 lb against the 11.4 lb stock muffler. Made in the USA.
