Evolution exhaust systems for the BMW 340i are the result of the perfect integration of expertise, the best technology, and the use of the finest materials. Made of austenitic stainless steel, these systems feature a layout with two central mandatory link pipes replacing the single stock pipe. The system is finished with carbon fibre tailpipes. This sporty elegance makes this Bavarian machine stand out from the rest and offers the taste of a more powerful version, accentuated with the additional power gains and weight losses of the Evolution performance exhaust system. The dual-mode ECU-controlled valve exhaust from Akrapovič offers stock-level sound at normal cruising, and a joyful deep sporty note when driving the 340i more dynamically. The Evolution systems replace the stock exhaust from the catalytic converters back.

The high-flow downpipe is constructed using high-quality stainless steel and, once fitted to the Evolution Line exhaust, it creates a complete system from the manifold to the tailpipes that will further enhance the performance figures: both the torque and power outputs. It incorporates a sporty catalytic converter – which is type-approved to meet ECE regulations, making the whole system ECE compliant – and so no remapping is needed for this performance upgrade. This optional downpipe produces an enhanced sound that delivers a pure racing emotion and fantastic feedback at high revs, without unwanted drone, making it suitable for everyday use.
Cars equipped with Akrapovič exhaust systems benefit from additional performance and increased responsiveness.
