The factory optional BMW M Performance diffuser reduces the 5mm of minimal side-to-side / up-down tip clearance recommended by Akrapovic.
If the vehicle has the M-Performance diffuser, fitment is not confirmed as the clearance range is reduced which could cause damage from heat.
This is a high-grade lightweight titanium system, with an option of round or hexagonal carbon-fibre and titanium tailpipes (the choice of one is mandatory). Complex parts, such as the X-connection and specially designed collectors, are cast at the in-house titanium foundry. The exhaust system has no exhaust valves, and the main exhaust tubes have an increased diameter. A special control kit operates the exhaust valves. Alongside acoustic reflectors on the tailpipes, a special resonator, and the X-connection, which allows gases from both sides of the engine to mix, these elements create a refined Akrapovič sound experience in all drive modes, delivering a deep and sporty tone. An additional damping element is added to the link pipe, which enhances the sound quality and comfort of the Akrapovič exhaust, while offering a unique sound experience. Power gains of 8.5 kW (11.5 hp) at 6,150 rpm and torque increases of 15.6 Nm at 2,550 rpm have been recorded when tested on the Akrapovič dyno against a BMW M5 with a standard stock exhaust. This exhaust system is 41.1% (15.44 kg) lighter than the standard stock version.
It has been developed for cars without gasoline particulate filters. The installation is a simple plug-and-play operation, with no remapping needed.
Notice: Performance tests and sound recordings were made with OPF vehicle.
