The Seletron XPF OPF-GPF Emulator is the ultimate solution for anyone who wants to get the maximum sound and power out of their BMW fitted with an S63B44T4 4.4 Twin-turbo V8. This system allows you to remove the OPF/GPF particulate filter without triggering any OPF-related fault codes, the engine fault light or limp mode. Thanks to its plug-and-play design, installation is simple, quick and fully reversible.
The emulator electronically simulates the presence of the particulate filter, ensuring the ECU does not register a fault in the OPF/GPF system. Ideal in combination with an OPF-delete mid-pipe or sports downpipes, allowing the full sound of the V8 to come back to life.
