Overview

The BMW G16 M850i Gran Coupe and Alpina B8 deliver incredible performance and refinement—but their stock exhaust note leaves room for excitement.
Our Valvetronic Designs Valved Exhaust System is engineered specifically for this platform to enhance presence, sharpen tone, and add measurable performance gains.

This full system bolts directly to the OEM downpipes or can be paired with a free-flow front race pipe setup. Valve operation integrates seamlessly with the factory Sport and Sport+ driving modes, allowing instant sound control from the driver’s seat. As a direct OEM replacement, it installs with no modifications and is guaranteed to deliver a richer, more engaging soundtrack through the entire rev range.
