High-quality DPF Delete Downpipe for BMW E60, E61 525d, 530d pre-facelift models with M57N (M57TU) engine. Exclusively crafted by KPerformance, our full 3″ downpipe maintains a bolt-on fitment while maximizing exhaust flow and minimizing backpressure, resulting in sharper throttle response, increased performance, and a deeper, more aggressive exhaust tone. Designed for vehicles with Euro 4 emission standard (produced from 2004 onward), which are equipped with a separate Diesel Particulate Filter (DPF) and an electronic turbo actuator. Important: While all 525d models are Euro 4, early 530d models from 2003–2004 can be either Euro 3 or Euro 4. Keep in mind that Euro 3 models with a vacuum-operated turbo actuator do not have a DPF. Please verify your car’s emission standard before ordering, or contact us if you’re unsure.
