Downpipe BMW E90, E91 318d, 320d M47N2 (Euro 3)

High-quality downpipe for BMW E90, E91 318d, 320d with M47N2 (M47TU2) engine.

Exclusively crafted by KPerformance, our full 3″ (76mm) 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.

Important: This downpipe has a 55 mm connection to the exhaust, which will only fit cars with Euro 3 emission standard (quite rare for E90/E91 models).
We also have a more common Euro 4 version with a 61 mm connection, so please verify your car’s emission standard before buying or consult with us.
