Akrapovic Slip On Line (Titanium) - BMW 4 Series G22 | G23 M440i (OPF/GPF)

Lighter, more powerful and far more vocal, the Akrapovic Slip-On Line (Titanium) for the OPF/GPF BMW M440i is made from high-grade titanium and finished with hand-made carbon-fibre tailpipes.

Two valves (the factory system has one) and two acoustic reflectors on the tailpipes shape the sound and direct it into the cabin, while resonators either side of the central muffler refine the tone. It stays smooth when cruising and turns deep and sporty when you press on.

• Power: +3.4 kW (4.6 hp) at 2,650 rpm
• Torque: +12.4 Nm at 2,650 rpm
• Weight: 11.89 kg lighter than stock (33% saving)

Please note: Supplied with carbon-fibre tailpipes and a TNG controller to operate the additional exhaust valve. The optional Akrapovic Sound Kit allows sound control from the cabin.

Please note: ECE type approved with no remap required. This system only fits OPF/GPF-equipped vehicles and the ECE certificate is valid for these cars only.

Please note: An additional stock BMW valve actuator (part no. 18 30 8 686 640) is required for installation.
