Offering a remarkable weight saving, increased power and torque, and a dramatic soundtrack, this system is constructed from high-grade lightweight titanium and completed with handcrafted carbon fibre exhaust pipes. The system offers a saving of 11.89 kg over the standard stock system, an incredible difference of 33%. Power and torque are increased by 3.4 kW (4.6 hp) at 2,650 rpm and 12.4 Nm at 2,650 rpm when tested on the Akrapovic dynamometer against a BMW M440i with a standard stock exhaust. A thrilling soundtrack is provided through the use of special parts fitted to the system. Two valves – instead of one as in the stock setup – are calibrated to adapt the sound, and two acoustic reflectors are fitted to the exhaust pipes to guide the sound into the car’s cabin and change the driving experience, producing a fully immersive sound in the car’s cockpit, to provide thrills and pleasure that can be enjoyed by all occupants. Because the Akrapovic Slip-On Line (Titanium) exhaust system has two valves, one more than the stock setup, a TNG controller is included with the product to activate the additional exhaust valve. Two resonators, one on each side of the central muffler, enhance the sound experience. The smooth, rich sound at normal cruising rises to a deep, sporty soundtrack when driving with more enthusiasm, and the tones can also be controlled from inside the cockpit with the addition of the optional Akrapovic Sound Kit. Special parts are cast in Akrapovic’s in-house foundry to create the intricate and complex items required for this system. It meets ECE type approval, and no remapping is required for this setup (the system only fits vehicles equipped with the OPF filter, and the ECE certificate is valid only for these cars; for vehicles without OPF, an Evolution Line system is available). An optional link pipe set is available for customers looking to upgrade to the Slip-On Line (Titanium) exhaust system. Fitment Notice: This product fits the BMW M340i equipped with an OPF. An extra stock valve actuator (part no. 18 30 8 686 640) is required when installing the Slip-On exhaust system on the BMW M340i (G20, G21) and M440i (G22, G23, G26). This product also fits the BMW M340i xDrive Touring (G21) model.
