Replace the restrictive factory diesel particulate filter (DPF) section with this Wagner Tuning downpipe kit, engineered for BMW's 3.0-litre N57 tri-turbo diesel engine. Removing the OEM DPF housing reduces exhaust back pressure, lowers thermal load on the turbocharger, and delivers a noticeable gain in power and torque.
