Active Autowerke F3X 340i 440i Valved Rear Exhaust GEN 2
Active Autowerke F3X 340i 440i Performance Valved Rear Exhaust GEN 2 is a valved rear exhaust system engineered for BMW F3X 340i and 440i models. The valved design lets the driver control exhaust sound, shifting between a quieter, more restrained tone and a full, aggressive note.
As the GEN 2 version of Active Autowerke's valved rear exhaust, this system is purpose-built for the F3X 340i and 440i platform. It is a direct-fit rear exhaust upgrade that replaces the factory rear section while retaining valve functionality for everyday drivability.
