This brand-new complete exhaust system for the Yamaha R9 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.
A high-grade lightweight titanium muffler outer sleeve and end cap is combined with a stainless-steel link pipe, headers, and pre-muffler. Developed to fit the motorcycle’s lines, a pre-muffler is positioned under the body and hidden by the lower fairings, and the muffler exits on the right side for a racing appearance. A catalytic converter is incorporated within the system to meet EC/ECE type approval (Euro 5+). It is supplied with an aluminium muffler bracket, and it delivers a deep and sporty sound.
Akrapovič engineers focused on throttle response during the development process and performance gains in the mid and high rev range. There are power and torque increases of 2.2 kW (3.0 hp) at 10,000 rpm and 2.6 Nm at 9,500 rpm, respectively, when tested on the Akrapovič dyno and compared to a Yamaha R9 equipped with a standard stock exhaust system. The plug-and-play installation means no remapping is required.
