Just installed this downpipe on my 2017 730i, and I'm genuinely impressed. The build quality is solid, and the fitment was spot-on—no modifications needed. After installation, I noticed a significant improvement in throttle response and a more aggressive exhaust note, especially during acceleration. It’s not overly loud, which I appreciate for daily driving, but it definitely adds some character. For the price, this upgrade is a no-brainer.
