Emissions Compliance Declaration: QUALIFIED MANUFACTURER DECLARED "MODIFIED PART"


WARNING: Cancer and Reproductive harm - www.p65warnings.ca.gov


The 2021 Yamaha MT-09 has been revised with many features including a refined chassis and engine package.

Our R&D team immediately went to work on the development for the new Yamaha and called on our AT2 profile to handle the power and torque of the 890cc three cylinder - torque monster engine. The AT2 is perfect styling for the MT-09 and incorporates our exclusive Works Finish an aggressively styled matte finish carbon fiber end cap complimented by a facet-formed tip while adding an aggressive GP tone.

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.

    Looks Good & Sounds Good

    Looks good on the bike and sounds awesome. I like a loud exhaust but didn't want something that was so loud it would be obnoxious. This is definitely loud but I wouldn't say it's obnoxiously loud or drones. It seemed just fine with my helmet on. If it was just a little bit louder it would be reaching into obnoxious territory. I almost went with SC-Project but decided to go with this because I always wanted a Yoshi system and I was worried the SC-Project might actually be too loud. After hearing this I am glad I chose this exhaust because it is the perfect volume in my opinion. Note I am not using the sound insert. Overall very happy.

    Looks and sounds great but

    It looks great and sounds great, but after getting my bike tuned I found out I had an exhaust leak so I sprayed the whole exhaust with soapy water figuring and there were three leaks from the two H-pipe sections and one from the weld where the three pipes join. The install wasn't too bad though it went on relatively easy but removing some of the wire sheething to extend the O2 sensor to reach the new spot was a pain. It was an early run so they might have fixed the quality now.

    Sorry or the issues.. please contact our customer service line (1-800-634-9166) to get these issues resolved. After you speak with one of our reps we will do our best to get this handled ASAP.

    Perfect sound and looks great!

    Amazing exhaust that maintains the “under-the-bike” look of the 2021 models. Easy to install as the headers and can are the only two pieces. The matte works finish looks great and will “bronze” better and more evenly than a glossy stainless finish. It sounds amazing - not crazy loud, but really brings out the triple. I’m using the sound insert, so it can be louder if you want. Yoshimura did an amazing job for the 3rd gen MT-09.
