BMW F20 / 21/22/23/30/31/32/33 M140i / M240i / 340i / 440i Akrapovic downpipe with cat stainless steel

Product description

The high-flow downpipe is made from high-quality stainless steel and, once fitted to the Evolution Line exhaust, it creates a complete system from the manifold to the exhaust pipes that will further improve the performance figures: both torque and power. It includes a sports catalytic converter - which has been type-approved to meet ECE regulations, making the entire system ECE compliant - so no remapping is required 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 an optional product for 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) - MTP-BM / SS / 2H + E-BM / SS / 2
