Akrapovič Evolution exhaust package, BMW M340i G20/G21 and M440i Gran Coupé G26 non-OPF

Akrapovič Evolution Line exhaust package – BMW M340i G20/G21 and M440i Gran Coupé G26 non-OPF

Akrapovič develops materials, structure and sound as one complete system. Months of development refine both performance and the sound character until everything is in tune. Manufacturing takes place in Akrapovič’s own facilities, with intricate cast components made in its own foundry. At Futurez, we have proudly served as an Akrapovič importer for over a decade.

The Evolution Line for the BMW M340i and M440i Gran Coupé combines a lightweight, high-grade titanium rear exhaust with an austenitic stainless-steel link pipe set. Hand-crafted carbon fibre tailpipes contain two acoustic reflectors that direct part of the sound towards the cabin. Intricate components are cast in Akrapovič’s own foundry.

Two resonators developed for this engine shape a deep, rich and sporty straight-six sound, with a design intended to avoid unwanted drone. The system has two valves rather than the single stock valve. An included TNG controller operates the additional valve.

Akrapovič tested the Evolution configuration on a BMW M440i against its stock exhaust. The measured configuration includes the titanium rear exhaust and stainless-steel link pipe set.
