Downpipe BMW X5 E70, X6 E71 30sd, 35d, 35xd M57N2

Performance 3″ (76 mm) downpipe designed for BMW X5 and X6 models equipped with the M57N2 (M57TU2) 3.0 diesel engine. Developed by KPerformance, this upgrade delivers improved exhaust flow while preserving a precise bolt-on installation. By reducing backpressure, it enhances turbo efficiency, sharpens throttle response, and provides a deeper, more aggressive exhaust note.
