Development with an emphasis on aesthetics, sound, and weight reduction led to this newly designed titanium muffler with an imprinted surface to add strength and durability. It offers a deep sound and a weight saving of 42.2% (1.8 kg) over the standard stock system. A carbon-fibre end cap and heat shield complete the look, with a stainless-steel link pipe and the inner structure of the muffler completing the system. During the development phase, Akrapovič engineers focused on throttle response, and performance has been boosted by an increase in power of 0.8 kW (1.1 hp) at 7,900 rpm and a torque rise of 1.0 Nm at 8,000 rpm when compared with a standard stock exhaust and tested on the Akrapovič dyno. It meets EC/ECE type-approval certificate - Euro5+, the new regulation from 2024 onward. The previous regulation, Euro5, was valid until 31 December 2023. The plug-and-play installation means no remapping is required.
