Transform the performance and sound of your BMW B48-powered vehicle with our Performance Downpipe, engineered specifically for the 2025+ BMW G20 320i/330i and G22/G23/G26 420i/430i models. Designed to replace the restrictive factory downpipe, this upgrade improves exhaust flow, reduces back pressure, and allows your turbocharger to operate more efficiently.
The result is improved throttle response, enhanced turbo spool characteristics, and a deeper, more aggressive exhaust note. When paired with a proper ECU tune, this downpipe can help unlock significant horsepower and torque gains while maximizing the performance potential of your B48 engine.
Constructed from premium T304 stainless steel and featuring precision TIG welds, this downpipe is built to withstand extreme temperatures and demanding driving conditions. Whether your BMW is a daily driver or a weekend performance build, this upgrade delivers lasting reliability and performance.

Why Upgrade Your B48 Downpipe?
The factory downpipe is designed primarily to meet emissions and noise regulations, which can restrict exhaust flow and limit performance. Upgrading to a high-flow performance downpipe allows your turbocharged B48 engine to breathe more efficiently, resulting in improved responsiveness, stronger acceleration, and a noticeably more aggressive exhaust tone.
