Akrapovič Downpipe w Cat (SS) for BMW M340I (G20, G21) / BMW M440I (G22, G23) … (DP-TY/SS/1)

This product is crafted from high-quality stainless steel, with the front part of the downpipe cast in Akrapovič’s in-house foundry. A sporty 300 cpsi catalytic converter is integrated into the downpipe, with the heat insulation made of stainless steel and a flexible tube incorporated into the middle section. Power gains with an Evolution Line (Titanium) fitted with the Akrapovič downpipe of 18.7 kW (25.4 hp) at 5,600 rpm and torque increases of 34.7 Nm at 2,400 rpm have been recorded when tested on the Akrapovič dyno against a BMW M440i with the standard stock exhaust. It delivers a pure racing sound, full of emotion and adrenalin-inducing enjoyment, and great feedback at high revs, all without unwanted drone. This product is meant for racetrack use only, and remapping the ECU is mandatory in order to prevent potential “check engine light” warning signals.The downpipe is an optional product for the following Evolution Line (Titanium) exhaust systems:BMW M340I (G20) without OPF/GPF: Slip-On Line (Titanium) + Evolution Link pipe (SS) - S-BM/T/17H + E-BM/SS/8BMW M440I (G22) without OPF/GPF: Slip-On Line (Titanium) + Evolution Link pipe (SS) - S-BM/T/18H + E-BM/SS/8Fitment notice: Product does not fit on cars equipped with B58TÜ2 engine.THIS PRODUCT DOES NOT MEET EMISSION COMPLIANCE REQUIREMENTS FOR STREET OR HIGHWAY USE.
