Resonator/OPF delete
Hello everyone, I have a 2023 330i, and I am looking into different exhaust setups. I recently saw a 330i with a resonator/opf delete, and I like the sound of it. My question is: will the opf delete void my warranty and/or throw codes? I have already spoken to a bmw technician about the resonator delete, but now I am realizing that the resonator and OPF are connected, so I would probably have to take both out. I definitely want to avoid having any issues with the engine or with the warranty, and I definitely do not want CEL or limp mode. Please let me know, and save me from some possible issues 😅

OPF?
Pretty sure that's only on ROW-spec B48s? You have a US-spec 330i, yes? You'd have a B46 without OPF. |

Wait, my car doesn’t even have a b48??? I had no idea! I swear I saw videos from the US where the resonator was half resonator and half opf. Thanks for the info

Thanks to California, the entire US has been blessed with the SULEV B46. The rest of the world gets the beefed up B48, albeit with an OPF. |
