BMW 440i (F32, F33, F36) Downpipe with Cat

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.
