Quicksilver Center Exit Sport Exhaust with Sound Architect (Inc. Carbon Diffuser Kit) for BMW M4 2021+

The QuickSilver and CarbonWurks BMW G8X Center Exit Sport Exhaust with Sound Architect is built for drivers who want full control over sound and performance. Designed for the BMW G80 M3 and BMW G82 M4, this system features an M Performance Exhaust inspired V layout, paired with a pre preg carbon fiber diffuser and carbon exhaust tips that match the look of a serious performance build. The factory exhaust often feels restricted and quiet. This upgrade delivers increased volume, a deeper exhaust sound, and responsive valve operation that reacts to how you actually drive.

From the factory, WLTP valve programming and active sound suppression limit the exhaust experience on the BMW G80 and BMW G82 platform. Below 30 mph, valves remain closed in most driving modes, even under moderate acceleration. When you lift off the throttle, they close again. This reduces the signature inline six sound these cars are known for. With the QuickSilver Sound Architect, you regain full control. Use the mobile app to open or close the valves whenever you want. The system no longer overrides your input. You can keep the valves open in any drive mode, giving you a more engaging and consistent driving experience.

This exhaust system uses a resonated H pipe design to produce a smoother, more refined tone without unwanted cabin drone. The full system runs 76mm piping throughout for improved exhaust flow. With the valves open, the silencer is bypassed, delivering aggressive sound with noticeable crackles and pops during deceleration. Close the valves and exhaust gases route through a triple chamber system, keeping the car quiet and comfortable for daily driving or long trips. The 101mm carbon fiber exhaust tips complete the setup with a premium finish that enhances the rear profile of the car.
