Developed exclusively for the BMW R 1300 GS from years of experience working with the BMW GS range and its boxer engines. A double flow muffler constructed from lightweight titanium and a handmade carbon-fibre end cap gives a weight saving of 9.3% over standard stock. Created for improved performance and enhanced sound silencing, which mitigates the impact on the environment, whilst delivering a deep, full sound. A special profiled surface on the muffler adds strength and durability and is finished with an engraved logo. Power and torque increases of 1.4kW (1.9hp) at 7,600rpm and 4.5Nm at 2,300rpm. These figures were obtained in back-to-back runs on the Akrapovič dyno against a BMW R 1300 GS using a standard stock exhaust. EC/ECE-type approval, simple plug and play installation with no remapping required. Once installed the system is all fully compatible with BMW Motorrad's side cases.
