Product details

Akrapovic Complete Exhaust System S-Y9R21-EET For Yamaha R9

This complete racing exhaust system for the Yamaha R9 combines a high-grade titanium muffler outer sleeve and end cap with stainless-steel headers and link pipe, delivering a lightweight and performance-focused upgrade.

Designed to follow the styling of Akrapovic systems developed for the Yamaha R6, R7, and R1, the exhaust takes clear inspiration from the units used in the World Supersport Championship. The result is a sharp, race-oriented appearance that perfectly complements the aggressive lines of the R9.

The muffler exits on the right side of the bike for a true racing look and is supplied with a durable aluminium muffler bracket for secure mounting.

Developed strictly for closed-course competition use only, this system does not include a catalytic converter or pre-muffler. As a result, ECU remapping is mandatory for proper operation and optimal performance.

  • Complete racing exhaust system for Yamaha R9

  • Right-side muffler exit for race styling
  • Aluminium muffler bracket included
