Unlock the performance potential of your BMW B58-powered vehicle with the Boosted Engineering 4-inch High Flow Downpipe System, designed for 2019+ M340i, M440i, and M240i models.

The upgraded 4-inch diameter design significantly improves exhaust flow compared to the restrictive factory downpipe. By reducing backpressure, this system allows the turbocharger to spool faster, resulting in improved throttle response, increased horsepower potential, and a deeper, more aggressive exhaust tone.

Manufactured using high-quality heat-resistant materials and precision welding, the downpipe ensures durability and reliable performance even under high boost and demanding driving conditions. The system is engineered for OEM-style fitment, allowing straightforward installation using factory mounting points.
