This listing is for NON-OPF M140i models (F20/F21) only.
The Evolution Line Stainless Steel back box with Carbon Fibre exhaust tips is 1kg lighter than the OEM back box, whilst providing increases in torque and BHP. There are slight differences in the back box between OPF and Non-OPF models, so select your model from the drop-down options above.
The exhaust system also comes with the Stainless Steel Evolution Link pipe, which replaces the single standard pipe with two central pipes.
Akrapovič have measured the Evolution Line back box, complete with Evolution Link pipe fitted, as delivering an extra 6bhp at 5500rpm and 13Nm of torque at 3000rpm.
There is also the option to spec a Stainless Steel downpipe fitted with a sports cat, which can be used in conjunction with the Evolution Line backbox and Evolution Link pipe. When fitted with the rest of the Akrapovič exhaust system, Akrapovič have measured increases of 18bhp at 5900rpm and 17Nm at 4000rpm over the standard car.
We offer fitting for all exhaust systems at our workshop in Stratford upon Avon - please get in touch for a quote.
