This high-grade lightweight titanium system, finished with hand-crafted carbon-fiber tailpipes, weighs in at 32.7 % lighter than stock and features a pair of collectors cast in the in-house foundry. The Slip-On Line (Titanium) comes with a specially developed Akrapovic control kit for a complete sound experience. The sound character offers a rich tone at normal cruising, rising to a deep sporty sound when the M2 is driven more dynamically. It serves up a perfect sound at all rpms, delivering comfort and sportiness in one exhaust. A ground-breaking octagonal shape has been fashioned from lightweight titanium with a carbon-fiber outer sleeve for the tailpipes, and for more traditional buyers there is the classic cylindrical design.
The system delivers power increases of 3.9 kW (5.3 hp) at 2,800 rpm and a torque gain of 13.5 Nm at 2,800 rpm when tested on the Akrapovic dyno against a BMW M2 with a standard stock exhaust. Remapping is not needed for this configuration, and it fits all vehicles (OPF and non-OPF).
Optional link pipes and downpipes are available for customers looking to change the exhaust for closed circuit usage. An optional Akrapovic Sound Kit is also available. With the installation of the optional link pipes, downpipes, and Akrapovic Sound Kit, ECE type approval of the Slip-On Line (Titanium) is no longer valid. An optional hand-crafted Carbon-Fiber Rear Diffuser is also available to add an extra visual impact to the Akrapovic tailpipes.
