A complete AT2 system for the 2017-on Ninja 650 and Z650, stainless from the headers to the muffler, with the AT2's faceted tip and Yoshimura's Works Finish. It takes the exhaust from 17.8 lb stock to 9.1 lb, and on Yoshimura's dyno it added 6.5% peak horsepower and 3.1% peak torque. It is loud: Yoshimura measured 103 dB at 5,000 rpm with the INS-20-K low-volume insert fitted, against 93 dB stock.
