The Evolution Line exhaust system will propel the BMW M240i to the next step of performance tuning due to an increase in torque and power. Impeccably designed to fit perfectly within the lines of the car, this austenitic stainless steel system is finished with hand-crafted carbon-fiber tailpipes to increase the visual impact. It has a layout incorporating two central link pipes to replace the stock single version, designed for optimum flow of the exhaust gases. A dual-mode ECU-controlled valve manages the sound levels, which ultimately delivers a deep and fulfilling sporty note as the revs rise.
