DD EXHAUST exhaust system with valve control for BMW M4 from OPF

During the development of the DD EXHAUST flap system, the focus was on the perfect optics and, above all, on the sound in combination with the OPF. The result is a balanced sound that is characterized by a clear and powerful sound and the so-called “pop and bang”. The whole thing is rounded off by a booming-free and pleasant sound perception in the interior of the vehicle.

Valve Module - OPTIONAL EXPANSION 529.-
Replace the original BMW valve module with our DD EXHAUST valve module and get even more sound out of your M4! The original valve modules do not open the valve 100% even when open. Our valve module allows the valve to open fully, making the system sound even more powerful. Of course, our valve module is also with ECE approval.
