AKRAPOVIC S-BM/T/31H Slip-On Line Exhaust System (Titanium) for BMW M440I (G22/G23) 2021-2024

Offering a noticeable weight saving, increased power and torque, and a dramatic sound, this system is crafted from lightweight, high-quality titanium and features handmade carbon fiber tailpipes. The system offers a weight saving of 11.89 kg compared to the standard stock system, an incredible 33% difference. Power and torque are increased by 3.4 kW (4.6 hp) at 2650 rpm and 12.4 Nm at 2650 rpm when tested on the Akrapovič dynamometer compared to a BMW M440i with a stock standard exhaust system. An exciting soundtrack is created through the use of special components built into the system. Two valves – instead of the one in the standard configuration – are calibrated to tune the sound, and two acoustic deflectors are installed on the tailpipes to direct sound into the car’s cabin and change the driving experience, creating an immersive sound experience for all occupants. As the Akrapovič Slip-On Line (Titanium) exhaust system has two valves, one more than the standard configuration, the product includes the TNG controller to activate the extra exhaust valve. Two resonators, one on each side of the central muffler, enhance the sound. The smooth, rich sound during normal cruising transforms into a deep and sporty soundtrack during more energetic driving, and the tones can also be controlled from the cabin via the optional Akrapovič Sound Kit. Special parts are cast in Akrapovič’s own foundry to create the intricate and complex elements required for this system. It is ECE type-approved, and no remapping is required for this configuration (the system is only suitable for cars equipped with an OPF filter, and the ECE certificate is only valid for these cars; for cars without OPF, the Evolution Line system is available). An optional link pipe kit is available for customers who wish to upgrade the Slip-On Line (Titanium) exhaust system.

Note: This product fits the BMW M440i equipped with OPF.

When installing the Slip-On exhaust system on the BMW M340i (G20, G21) and M440i (G22, G23, G26), the optional standard valve actuator (part no. 18 30 8686640) is required.

This product also fits the BMW M440i xDrive Cabriolet (G23).
