Downpipe BMW E60, E61 525d, 525xd, 530d, 530xd M57N2

(76mm) downpipe designed for BMW 5 Series models equipped with the M57N2 (M57TU2) engine. Manufactured by KPerformance, this upgrade is built to deliver improved exhaust flow while retaining a precise bolt-on installation. By reducing backpressure, it enhances turbo efficiency, sharpens throttle response, and produces a deeper, more dynamic exhaust sound.
