Yoshimura AT2 Slip-On Exhaust w/Stainless Muffler

The all-new highly anticipated Kawasaki Ninja 500 can now be upgraded with our AT2 Street Series slip-on and Fender Eliminator Kit. Designed to enhance both performance and aesthetics, these cutting-edge products offer Kawasaki fans and enthusiasts a power-packed and stylish riding experience for the 451cc twin cylinder.
This AT2 system is also compatible with the Ninja 400 and Z400 as well!
The AT2 slip-on with carbon fiber heel guard delivers a perfect balance of style, power, weight reduction, and a deep, throaty exhaust note. Offering a max HP boost of 3.2% and torque increase of max 5.3% the AT2 packs a nice performance increase over stock. A 3.3 pound loss of weight over the stock unit lightens up unsprung weight with an incredible exhaust note that can only be Yoshimura.
Yoshimura's AT2 is proudly designed, developed and manufactured in Chino, California.
