As the GPF/OPF almost acts as a secondary catalyst, Miltek have provided the option to remove this component, similar to a Decat system. This bypass deletes the GPF/OPF, removing it from the exhaust system to better improve performance. – GPF/OPF Bypass software is required on the vehicles ECU in most cases.
