I may sound like an idiot asking this but I switched over from a catless downpipe to a high flow Downpipe after having some issues with the law. After a day or so of driving I’ve gotten this code claiming that the catalytic converter is performing below threshold. I did not replace the o2 sensors when I swapped it which I should have considering they were very black, and burble kills o2 sensors pretty quickly. I also went from a tune that was clearing o2 codes to a tune that doesn’t so I would assume that my o2 sensors are dead??

Any thoughts anyone?
