Cleaning catalytic converter? Plausible

[@liorlevi3991]

Wow that's cool! I will try it for the next test as well !. There's something I noticed, you have 2 catalytic converters, I have one and I do not have 2 oxygen sensors, only one. Probably because I have an older model

I would really love to see updates later

Yep, after 2001 in the EU it became mandatory to sell petrol cars with at least Euro 3, equipped with EOBD (basically OBD2) port and a check engine light. In order to meet Euro 3, Mazda equipped warm up catalytic converter, which is the one that causes me issues (P0421). We'll see if issue persists.
