Description

Developed by Yoshimura as part of their ProjectR7 build series featuring Ari Henning, and tested by 2022 MotoAmerica Twins Cup Champion Blake Davis, this Yoshimura Race Series AT2 Full System Exhaust is ready to take your Yamaha to the podium. This kit is modeled after the full titanium version, this Works Finish stainless system balances performance and value. Yoshimura developed this exhaust to be paired with heavily modified race engines, but is capable of producing significant gains even on a fully stock and unmodified engine. During their testing on a stock R7 running 91 octane pump fuel, the team at Yoshimura found that this exhaust system can boost max horsepower by 5.7% and max torque by 2.7%. Pair this exhaust with a race-developed airbox and ECU tune and you’ll quickly find that those figures are just the start of your performance gains!
