Milltek Sports Exhaust Gas Particulate Filter Bypass Pipes. OAP Porsche 718 Cayman GT4 / 718 Boxster GTS 4.0L
As the GPF/OPF almost acts as a secondary catalyst, we 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.
