Description

Akrapovic S-Y9R21-EET Racing Cat Delete Full Exhaust Titanium Ti Muffler R9 YZF-R9 

A high-grade titanium muffler outer sleeve and end cap is combined with a stainless-steel link pipe and headers. It is a complete exhaust system for the Yamaha R9 that follows the look of the Akrapovič exhaust systems for the Yamaha R6, R7, and R1, with a design similar to the Akrapovič exhausts used in the World Supersport Championship.

The muffler exits on right side of the bike for a racing look, and it is supplied with an aluminium muffler bracket. Developed for closed-course competition circuits only, this system has no catalytic converter or pre-muffler, and so ECU remapping is mandatory.

Please notice that two different noise inserts are offered with the product.
