PPF/OPF points on deleting resonators on newer M240i?
I used to be about to take my M240i to an exhaust store to get the resonators eliminated however I noticed on babybmw that lots of people had been throwing CELs due to the PPF (or OPF or GPF no matter you could name it) being monitored. Is anybody within the US coming throughout this? My automotive is so quiet I actually needed these resonators gone however I’d hate to throw CELs due to that PPF within the first resonator.
