Akrapovic Titanium/Stainless 3-1 Racing Line Exhaust System (S-Y9R21-EET)
- High-grade titanium muffler outer sleeve and end cap is combined with a stainless-steel link pipe and headers
- Follows the look of the Akrapovic exhaust systems for the Yamaha R6, R7, and R1, with a design similar to the Akrapovic exhausts used in the World Supersport Championship
- Muffler exits on right side of the bike for a racing look, and it is supplied with an aluminum muffler bracket
- Developed for closed-course competition circuits only, this system has no catalytic converter or pre-muffler, and so ECU remapping is mandatory
