This product is totally constructed from high-grade titanium and features special parts, with two valves, one for each side of the muffler, and two acoustic reflectors. The housing of the valves and the collectors are all cast in the in-house titanium foundry. There is a choice of two tailpipe designs: either the ground-breaking octagonal shape, as first seen on the exhaust for the BMW M3/M4, or the more traditional and classic design. The twin sets of tailpipes have outer sleeves hand crafted from carbon fibre, and the use of lightweight materials has produced an exhaust that is 7.3 kg (32.7%) in comparison to the standard stock exhaust.
Power is increased by 3.9 kW (5.3 hp) at 2,800 rpm and a torque gain of 13.5 Nm at 2,800 rpm was registered when tested on the Akrapovič dyno against a BMW M2 Coupé with a standard stock exhaust. The exhaust has been developed to provide a unique driving experience. Together with the most advanced Akrapovič control kit – which has been designed to offer an exceptional sound experience – the system with its exhaust valves and acoustic reflectors tailors the gas flow to a smooth, rich tone at normal cruising and a deep, sporty sound when driving the M2 Coupé more dynamically and enthusiastically.
ECU remapping is not needed, and the exhaust meets ECE type-approval conditions for the BMW M2 Coupé (G87) with OPF filters.
The Slip-On Line (Titanium) exhaust system is ECE type approved for cars equipped with an Otto/gasoline particulate filter.
