Exhaust Akrapovic Slip-On BMW 4 GRAN COUPE M 440 I XDRIVE MILD-HYBRID 01-21

Offering significant weight savings, increased horsepower and torque, and a spectacular soundtrack, this system is constructed from high-grade lightweight titanium and completed with hand-crafted carbon fiber tailpipes. The system offers a saving of 11.89 kg compared to the original exhaust, an incredible 33% difference. Power and torque increased by 3.4 kW (4.6 bhp) at 2,650 rpm and by 12.4 Nm at 2,650 rpm, values obtained on the Akrapovic dyno with a BMW M440i with stock exhaust. The system includes two valves - instead of one, as in the standard configuration - perfectly calibrated to adapt the sound, and two acoustic reflectors are mounted on the terminals to guide the sound into the car's cabin and change the driving experience. producing an immersive sound inside the car. Since the Akrapovic Slip-On (Titanium) 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, refine the sound experience. The smooth, rich sound during normal driving becomes a deep, sporty soundtrack when driving more enthusiastically, and the tones can even be controlled from the cockpit with the addition of the optional Akrapovic Sound Kit. Several special parts are cast in Akrapovic's in-house foundry to create the intricate and complex elements of this exhaust. The Slip-On is ECE compliant and no remapping is required for this setup (the system only fits vehicles fitted with an OPF/GPF filter and the ECE certificate is only valid for these cars; for non-OPF/ GPF, an Evolution system is available). An optional set of header pipes is available for those customers looking to upgrade their Slip-On Line (Titanium) exhaust. Fitment Notice: This product fits OPF/GPF equipped BMW M340i. This product also fits the BMW M340i xDrive Touring (G21) model.
