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.

Customer Reviews (5.0 / 5 · 5 reviews)

Riley ★★★★★

Took it to the track last weekend and the mid-range pull is noticeably stronger, plus the 3/4 length keeps the noise neighbor-friendly while still sounding mean. The stainless muffler tip already has a nice gold tint from heat, which looks killer on the bike.

Ryan ★★★★★

The AT2’s stainless construction feels solid and the 3/4 design sheds enough weight to make the front end noticeably lighter on turn-in. Sound is deep without being obnoxious on the street, and the welds look cleaner than anything I've had before.

Thomas R. ★★★★★

Installation took about 40 minutes with basic tools, and the tone is deeper than I expected from a 3/4 system—perfectly aggressive without being annoyingly loud on the highway.
