The Akrapovic Sound Kit for 2018–2020 BMW 340i (F30/F31) and 440i (F32/F33/F36) with OPF/GPF provides a vehicle-specific way to alter exhaust sound on those models. Packaged as a sound-control accessory, it is intended to integrate with the car's existing exhaust layout and deliver a refined change to exhaust note consistent with Akrapovic's sound kit offerings for late-model BMW applications.
