Akrapovic BMW 140i - 240i - 340i - 440i Downpipe w Cat (SS)
Description
Downpipe w Cat (SS) was tested and developed together with Evolution Line (Titanium) system.
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.
When installing the Akrapovic downpipe, remapping the ECU is mandatory in order to prevent potential "check engine light" warning signals.
Downpipe is optional product to the following evolution systems:
BMW M140i: Evolution Line (SS) - MTP-BM/SS/3H + E-BM/SS/3
BMW M240i: Evolution Line (SS) - MTP-BM/SS/4H + E-BM/SS/3
BMW 340i /440i: Evolution Line (SS) - "1MTP-BM/SS/2H + E-BM/SS/2"1
THIS PRODUCT DOES NOT MEET EMISSION COMPLIANCE REQUIREMENTS FOR STREET OR HIGHWAY USE.
