Akrapovič BMW M340i, M440i Evolution Line Exhaust System Now Available at Turn 14 Distribution

May 20, 2021

Akrapovič has released its BMW M340i (G20)/M440i (G22) Evolution Line (Titanium) exhaust system, which is now available at Turn 14 Distribution, the sole U.S. automotive distributor for Akrapovič, the distributor announced.

The Akrapovič Evolution Line is a high-grade lightweight titanium exhaust system, finished with hand-crafted carbon-fiber tailpipes and a high-grade austenitic stainless steel link pipe set, the company said. The valves on each side are designed to tailor the exhaust note, and two acoustic reflectors are fitted on the tailpipes to guide the sound into the vehicle’s cabin. The system incorporates two valves, one more than the stock configuration, so a TNG controller is included in the product to activate the additional exhaust valve. There are also two tuned resonators developed especially for this straight six-cylinder engine. These parts are cast in the Akrapovič in-house foundry.

The Evolution Line weighs 47.8 lbs, which is 23% lighter than the stock exhaust. Power gains of 11.8 horsepower at 5,600 rpm and torque increases of 12.6 lb.-ft. at 4,100 rpm were recorded while testing on the Akrapovič dyno against a BMW M440i with a stock exhaust, the company said.
