I watched both videos and see why you're confused, but frankly the two videos are different. To me your reading indicates a vacuum lean combined with a misfire, not a restricted exhaust. But I'm just seeing the video, perhaps something is getting lost by not being there in person.

At first i was confused but after all the test that I've done I'm sure its a bad cat along with a very big vacuum leak. the reason I'm sure is because there was a huge improvement only after i removed the bank 1 o2 sensor and when i put it back in the symptoms returned.
There might still be misfires and bad coils but i don't want to do anything until i can fix the vacuum leaks I'm just having a problem finding it.
