Sorry just posted this and then saw the videos. That thing is running pretty rough and that thing is red hot so you weren't exaggerating. I am surprised there are no codes.
However, now that I have seen that, your issue could be one of a couple things. First is a misfire so we need to suspect that coil.
Next, the converter could be clogged. Are you able to measure the back pressure? This is where you remove the o2 sensor and install a gauge made for this. If you don't have one don't buy one. Try removing the upstream o2 on that side and see if the engine smooths out. It is going to be loud but a clogged converter can glow and cause rough running. If you want to an exhaust shop can measure back pressure and it is pretty cheap. Cheaper then guessing at replacing the converter.
After that, we have to suspect internal engine issues as valve issues or piston ring issues.
Clearly with that glowing that red, it is a safety issue. That can catch the surrounding components on fire so be careful.
