3DDesign Exhaust Dual-Valve Controller for Gxx BMW M2, M3, M4, and M850i / U25 MINI Countryman JCW [4191-00102]

The 3DDesign Exhaust Dual-Valve Controller offers precise, on-demand control over the factory electronic valves on select BMW and MINI models, including the G87 M2, G80 M3, G82 M4, G16 M850i, and U25 MINI Countryman JCW. Designed to integrate seamlessly with the factory valve actuators, this controller allows drivers to manually open or close both exhaust valves regardless of drive mode, enabling full exhaust flow for an aggressive tone or closed-valve operation for a more subdued experience. Engineered with 3DDesign’s signature attention to quality and usability, the unit ensures reliable performance without triggering error codes or affecting drivability. Ideal for enthusiasts seeking greater control over their exhaust sound, this plug-and-play solution maintains OEM functionality while adding a new level of flexibility.
