BMW 4 Series 440i F32 / F33 Akrapovic Downpipe Stainless Steel
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 – which is type-approved to meet ECE regulations, making the whole system ECE compliant – and so no remapping is needed for this performance upgrade. 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: Evolution Line (SS) - MTP-BM/SS/3H + E-BM/SS/3
