Introducing the latest from our R&D 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. Never the ones to settle, we continually refine our offerings thus we have developed our new AT2 3/4 system for 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 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 2.1% 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! INS-20-K sound insert is supplied with this system.

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

Stock muffler weight: 16.1 Lbs. vs Yoshimura AT2 3/4 System weight: 5.3 Lbs.

New Yoshimura Works Finish takes on a unique coloring after it goes through a heat cycle on the motorcycle that looks much like those titanium works components our factory racers use.
