The Akrapovic Evolution Line (Titanium) cat-back for the 2021 BMW M440i (G22) delivers a lightweight titanium exhaust with hand-crafted carbon-fibre tailpipes and stainless-steel link pipes. It includes a TNG controller for an added valve, two tuned resonators and acoustic reflectors to shape a deep, rich sound. Weighing 21.7 kg it saves mass versus stock and showed measured power and torque gains on Akrapovic dyno. Not for OPF cars; track use only.
