Downpipe BMW F07, F10, F11 518d, 520d/dX, 525d/dX B47, N47N, N47S1 (Euro 6)

High-performance 3″ (76 mm) downpipe designed for BMW F0x 5 Series models equipped with B47, N47N, and N47S1 diesel engines. Crafted by KPerformance, this full-diameter downpipe ensures a precise bolt-on installation while optimizing exhaust flow. Reduced backpressure enhances turbo response, sharpens throttle performance, and delivers a deeper, more aggressive exhaust tone.
