Full Exhaust Type Muffler
The silencer for the YZF-R9 is designed based on the design adopted for the YZF-R1 and YZF-R6 in the World Supersport Championship. It is a hybrid-type full exhaust featuring stainless steel exhaust pipes and a titanium silencer. The JMCA-certified muffler, which meets increasingly stringent global emission and noise regulations, can be used with "peace of mind, safety, and comfort" for touring and in residential areas within Japan.

Akrapovic engineers focused on improving throttle response and mid-to-high RPM performance during the development process. Tests on an Akrapovic dynamometer showed an increase of 2.2 kW (3.0 hp) at 10,000 rpm and 2.6 Nm of torque at 9,500 rpm compared to the standard stock exhaust system.
