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