Akrapovic Slip On Line (Titanium) - BMW 3 Series G20 | G21 M340i | 4 Series G26 M440i Gran Coupe (OPF/GPF)

The Akrapovic Slip-On Line (Titanium) for the OPF/GPF BMW M340i and M440i Gran Coupe combines a significant weight saving with extra power and torque and a dramatic soundtrack. It is made from lightweight high-grade titanium and finished with handcrafted carbon fibre tailpipes.

Two valves (one more than standard) tailor the sound, while two acoustic reflectors on the tailpipes carry it into the cabin. Twin resonators either side of the central silencer give a smooth, rich tone when cruising that builds to a deep, sporty note when driven hard.

• Power: +3.4 kW (+4.6 hp) at 2,650 rpm
• Torque: +12.4 Nm at 2,650 rpm
• Weight saving: 11.89 kg (33%) compared with the standard system
• Tested on the Akrapovic dyno against a BMW M440i with the standard exhaust

Please note: this system fits OPF/GPF-equipped vehicles only; the ECE type approval is valid only for these cars. An Evolution Line system is available for non-OPF vehicles.

Please note: an additional genuine BMW valve actuator (part no. 18 30 8 686 640) is required when installing this system.

Please note: a TNG controller is included to operate the additional exhaust valve. No ECU remap is required.

Please note: the sound can be controlled from the cabin with the optional Akrapovic Sound Kit, and an optional link pipe set is available to upgrade the system.
