Akrapovic Exhaust System for BMW M140i (F20/F21)

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 split into 2 codes only because of packaging issues.

This system does not fit on vehicles equipped with Otto particulate filter (OPF).

Downpipe w Cat (SS) was tested and developed together with the Evolution Line.

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. 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.

Downpipe is optional product to the following Evolution systems:

• BMW M140i (non-OPF/GPF): Evolution Line (SS) - MTP-BM/SS/3H + E-BM/SS/3

Evolution Link Pipe Set (SS) was tested and developed together with Slip-On Line (Titanium).

The Evolution link pipe set upgrades the Slip-On system to the Evolution system. The Evolution link pipe set is constructed from high-quality austenitic stainless steel. It features an arrangement of two central link pipes, which replace the single-pipe stock design for the best flow of the exhaust gases from the engine. It is designed to increase power and torque and reduce overall weight, while delivering a deep and sporty sound with no unwanted drone or streaming, unleashing the pure straight six-cylinder sound.

When installing the Akrapovic Evolution link pipe set, remapping the ECU is mandatory in order to prevent potential "check engine light" warning signals.

This product does not meet emission compliance requirements for street or highway use.

The optional Akrapovic Sound Kit enables owners of selected Akrapovic car exhausts to control the sound of the system from the cockpit of their machine. Using Akrapovic technology, drivers can easily switch between the quiet mode and a sportier sound. With the use of a receiver to drive the actuators that open or close the valves at the end of the exhaust system, drivers can use the Sound Remote Controller to regulate the valves.

With the use of the optional Akrapovic Sound Kit, the ECE type approval is no longer valid.
