Downpipe BMW E60, E61 525d, 530d M57N (Euro 4)

High-quality 3″ (76 mm) downpipe designed for BMW E60 and E61 5 Series pre-facelift models equipped with the M57N (M57TU) diesel engine. Developed by KPerformance, this full-diameter downpipe ensures a direct bolt-on fit while improving exhaust flow, reducing backpressure, and delivering sharper throttle response, increased performance, and a deeper, more aggressive exhaust note.

Important Information

This downpipe is intended for vehicles with the Euro 4 emission standard (produced from 2004 onward), equipped with a Diesel Particulate Filter (DPF) and an electronic turbo actuator.

• All 525d models are Euro 4.

• Early 530d models from 2003–2004 may be Euro 3 or Euro 4. Euro 3 vehicles with a vacuum-operated turbo actuator do not have a DPF and require a different downpipe.

Please verify your car’s emission standard before ordering or contact us if you are unsure.
