Akrapovic BMW G20/G21 M340i & G26 M440i Gran Coupe OPF/GPF Slip On Line Titanium Exhaust System

Offering noticeable weight savings, increased power and torque, and a dramatic soundtrack, the Akrapovic BMW M340i & M440i Gran Coupe OPF/GPF slip on line titanium exhaust system is constructed from lightweight high-grade titanium and completed with hand-crafted carbon-fibre tailpipes. The system offers an 11.89 kg savings 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 Akrapovič dyno against a BMW M440i with a standard stock exhaust. An exhilarating soundtrack is delivered through the use of special parts fitted in the system. Two valves – instead of one, as in the stock configuration – are calibrated to tailor the sound, and two acoustic reflectors are fitted on the tailpipes 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 supply thrills and enjoyment that can be enjoyed by all occupants.

Because the Akrapovič Slip-On Line (Titanium) exhaust system has two valves, one more than the stock configuration, a TNG controller is included in the product to activate the additional exhaust valve. Two resonators, one on each side of the central muffler, perfect the sound experience. The smooth, rich sound at normal cruising rises to a deep and sporty soundtrack when driving more enthusiastically, and the tones can also be controlled from within the cockpit with addition of the optional Akrapovič Sound Kit. Special parts are cast in the Akrapovič in-house foundry to create the intricate and complex items needed for this system. It meets ECE type approval, and no remapping is needed for this configuration (the system only fits vehicles equipped with the OPF filter, and the ECE certificate is valid only for these cars; for non-OPF vehicles, an Evolution Line system is available). An optional link pipe set is available for those customers looking for an upgrade to the Slip-On Line (Titanium) exhaust system.
