This high-grade lightweight titanium system, finished with hand-crafted carbon-fibre 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) can include a specially developed Akrapovič 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-fibre 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 Akrapovič 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), but the ECE certificate is valid only for cars equipped with an OPF filter.
NOTE: The Slip-On Line (Titanium) exhaust system is ECE type approved for cars equipped with an Otto/gasoline particulate filter. With installation of optional link pipes, downpipes, and Akrapovič Sound Kit, ECE type approval is no longer valid.
