The Akrapovic Evolution exhaust systems for the BMW F22/23 M240i 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 newly developed layout with two central link pipes replacing the single stock pipe, a new muffler design, and carbon fiber tailpipes.

This Akrapovic Evolution exhaust improves upon the stock exhaust system of the BMW M240i in numerous areas. The first visible improvement is the additional power of 6.5 HP (at 5500 rpm) and 12.6 Nm (at 3000 rpm). The range between 2.000 rpm and 3.500 rpm  was particularly improved. A noticeable improvement can also be observed at high RPM where the Evolution gives more power. 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 system. The dual-mode ECU-controlled valve exhaust from Akrapovic offers stock-level sound at normal cruising, and a joyful deep sporty note when driving the M240i more dynamically. The Evolution systems replace the stock exhaust from the catalytic converters back.
