Downpipe BMW G11, G12 730d/Ld, 730dX/LdX, 740dX/LdX B57

High-quality downpipe for BMW G11, G12 730d, 730dX, 740dX, 730Ld, 730LdX, 740LdX models with B57 engine.

Exclusively designed by KPerformance, our full 4″ 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.

Fits Euro 6 vehicles with a 2-bolt flange-to-exhaust setup and a factory AdBlue/SCR system, which is bypassed when our pipe is installed.
