Offering a noticeable weight savings, increased power and torque, and a dramatic soundtrack, this system 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 Akrapovic 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 cars cabin and change the driving experience, producing a fully immersive sound in the cars cockpit, to supply thrills and enjoyment that can be enjoyed by all occupants. Because The Akrapovic 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 Akrapovic Sound Kit. Special parts are cast in The Akrapovic 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 (part nr. 18 30 8 686 640) is needed when installing the Slip-On exhaust system on BMW M240i (G42)..
