Yoshimura MT-09 2021 Race AT2 Stainless Full Exhaust, w/ Stainless Muffler

Right away the bike lost 6 pounds by removing the stock system and installing the AT2 Race Series full system. With plenty of torque on the bottom end we focused on bringing the power more to the top of the spectrum. After development and testing was all said and done the AT2 gave the MT-09 a nice 2.7% increase in max HP and a 1.6% in max torque.

Stock System: 15.6 Lbs. VS Yoshimura AT2 full system: 9.6 Lbs.

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