Akrapovič Evolution Line Titanium Exhaust System - G22/G23 M440i xDrive

A pioneer in its field, Akrapovic is widely recognised as a highly innovative materials technology company. The brand is synonymous with the highest level of design, performance enhancement and the creation of an unmistakable deeply resonant exhaust sound and style.

Product Information

This is a high-grade lightweight titanium system for G22/G23 M440i xDrive is finished with hand-crafted carbon-fibre tailpipes and a high-grade austenitic stainless-steel link pipe set. The valves in each side are calculated to tailor the sound, and two acoustic reflectors are fitted on the tailpipes to guide the sound into the car’s cabin. Because the Akrapovič Evolution 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. To make the sound experience even more unique, there are two tuned resonators – developed especially for this new engine – producing a deep, rich, and sporty sound with no unwanted drone or streaming, perfectly aligned with the straight six-cylinder engine. It weighs 21.7 kg, which is 23% lighter than stock. Power gains of 8.7 kW (11.8 hp) at 5,600 rpm and torque increases of 17.1 Nm at 4,100 rpm were recorded when tested on the Akrapovič dyno against a BMW M440i with a standard stock exhaust. Special parts are cast in the Akrapovič in-house foundry to create the intricate and complex items needed for this system. Meant for track use only and for non-OPF vehicles, remapping is recommended with this product.

Please note that both product codes, S-BM/T/31H and E-BM/SS/8, are included in this package.

Fitment notice: The Evolution Line (Titanium) only fits on non-OPF vehicles. For non-OPF vehicles, the ECE type approval certificate is not valid.

Suitable for G22 M440i xDrive Coupe and G23 M440i xDrive Convertible models only. Not for G26 M440i xDrive Gran Coupe.

I have used many mechanics over the years for the many different types of vehicles in our company fleet and southern BM is one of the very few workshops I can highly recommend. Andrew and his team are also really passionate about their work and it shows.

I Bought my M Performance Brake Kit here and installed today. I got my oil changed. Love the service as always. I only bring my cars to this place eventhough I live in the north side of Melbourne.
