Upgrade the performance and sound of your BMW M340i or M440i with the Akrapovič Evolution Line (Titanium) Exhaust System. Constructed from premium high-grade titanium and paired with a high-quality austenitic stainless-steel link pipe set, this lightweight exhaust system is engineered to reduce weight, increase power and torque, and deliver the signature Akrapovič driving experience. Featuring dual exhaust valves, acoustic reflectors, and specially tuned resonators developed for the turbocharged inline-six engine, it produces a deep, rich, and sporty exhaust note without unwanted drone.
Designed to create a more immersive driving experience, the Evolution Line directs a portion of the exhaust sound into the cabin through integrated acoustic reflectors, enhancing driver engagement while maintaining everyday comfort. Components cast in the Akrapovič in-house foundry ensure exceptional quality, durability, and performance. A TNG controller is included to operate the additional exhaust valve integrated into the system.
