OPF removal- Dont do it!
So I'll be the sacrificial donkey and share with community. Just don't do it. Yes sound without OPF with even stock center is awesome (perfect).......but the newest cars either have an ECU update or different cat monitoring algorithm. This leaves you with a CEL that won't go away even after clearing with newest PIWIS. Going to buy a new set of factory headers even though I absolutely love the sound.

Thank you for sharing this because I was planning on doing the same thing. However, my understanding was that only the EU spec'd cars will give you the CEL with the OPFs removed.

What engine fault code are you getting?

Hmm there is no active monitoring of the opf. Are you sure the cats weren’t damaged?

First time hearing this for U.S version. Other people on here did not have check engine light on after removing.
