This downpipe is developed for BMW 335d and 535d with the M57 diesel engine and fits E90, E91, E92, E60, and E61. It is made of stainless steel with a polished surface and is designed for improved exhaust flow compared to the original solution. The result is faster response and better utilization of the turbo setup. The product is intended for performance use, and engine management must be adapted after installation. Compatibility must always be confirmed before ordering based on model, year, and engine variant.
