Offering a noticeable weight savings, increased power and torque, and a dramatic soundtrack, the Akrapovič Slip-On Line System for the G42 M240i xDrive  is constructed from lightweight high-grade titanium and completed with hand-crafted carbon-fibre tailpipes. Power and torque are increased by 7.1 Kw (9.7 hp) at 2,450 rpm and 20.5 Nm at 2,450 rpm when tested on the Akrapovič dyno against a BMW M240i with a standard stock exhaust. An exhilarating soundtrack is delivered through the use of special parts fitted in the system. Two valves – instead of one, as in the stock configuration – are calibrated to tailor the sound, and two acoustic reflectors are fitted on the tailpipes to guide the sound into the car’s cabin and change the driving experience, producing a fully immersive sound in the car’s cockpit, to supply thrills and enjoyment that can be enjoyed by all occupants. Because the Akrapovič Slip-On Line (Titanium) exhaust system has two valves, one more than the stock configuration, a TNG controller is included in the product to activate the additional exhaust valve. Two resonators, one on each side of the central muffler, perfect the sound experience.

The smooth, rich sound at normal cruising rises to a deep and sporty soundtrack when driving more enthusiastically, and the tones can also be controlled from within the cockpit with addition of the optional Akrapovič Sound Kit. Special parts are cast in the Akrapovič in-house foundry to create the intricate and complex items needed for this system. It meets ECE type approval, and no remapping is needed for this configuration (ECE certificate is valid only for cars equipped with OPF). 

An extra stock valve actuator (BMW part number 18 30 8 686 640) is needed when installing the Slip-On exhaust system on BMW M240i xDrive (G42).

Suitable for G42 M240i xDrive Coupe models with or without OPF/PPF.
