The AKRAPOVIC S-K4SO9-HRT Slip-On Line Muffler is designed for the Ninja 7/Z7 Hybrid, combining a titanium muffler body with an imprinted surface intended to add strength and durability. A carbon-fiber end cap and heat shield complement the muffler’s appearance, while a stainless-steel link pipe and internal muffler structure complete the system.
Compared with the standard stock exhaust, this system provides a claimed weight saving of 42.2% (1.8 kg) and delivers a deep sound. Performance testing on the Akrapovic dyno showed an increase of 0.8 kW (1.1 hp) at 7,900 rpm and a torque increase of 1.0 Nm at 8,000 rpm. The system is focused on throttle response and uses a plug-and-play installation design, with no remapping required.
