The Evolution Line system will take the BMW M140i to the next level of exhaust and performance tuning. Designed to increase power and torque while also reducing weight, this perfectly sculpted system is constructed from high-quality austenitic stainless steel and finished with hand-crafted carbon-fibre tailpipes. For the best flow of exhaust gases from the engine, the system features an arrangement of two central link pipes, which replace the single stock-pipe design. Sound is enhanced through the use of a dual-mode ECU-controlled valve, which delivers a stock-level tone at normal cruising and an exciting deep sporty note as the driving gets more spirited. It is fully EC compliant and features simple plug-and-play installation for ease of use.?Please be aware that both part numbers: MTP-BM/SS/3H and E-BM/SS/3 have to be ordered! The system is splitted in 2 codes only because of packaging issues.Fittment notice: Exhaust fits also on vehicles with X-drive.This system does not fit on vehicles equipped with Otto particulate filter (OPF).
