Introducing the latest from our Research and Development team at Yoshimura - AT2 Street Series 3/4 system for the Kawasaki ZX-6R.

Without a doubt the Kawasaki ZX-6R is one of the hottest middle weight sport bikes in the market, 2019 brought a refresher to the 636cc green machine. Never the ones to settle, we continually refine our offerings thus we have developed our new AT2 system for the this racing legend.

This new system incorporates our exclusive Works Finish featuring an aggressively styled matte finish carbon fiber end cap and heal guard complimented by a facet-formed formed tip. Our AT2 comes in at an incredible 10.8 pound weight savings making this system a winner already!

The performance results were amazing in our development as well! More linear throttle response and torque made the ZX-6R come alive with max HP at 2.2% and peak torque gains of 4.7% the green machine is ready to rise to the top of the podium. Oh yeah, and that distinctive Yoshimura AT2 exhaust note will have your heart revving for more!

The AT2 is proudly developed, designed and made in the USA.
