Not a dumb question, but yes the bungs are just slightly above center in the pipes
Something different there than what I first though. I still think its fuel related, but I think you are going from pig rich to actually a bit lean WOT. Exhaust full of fuel and then hit with a massive amount of lean hot air is throwing fuel right at the sensor frying it. Just what I think, maybe one of the big guys here will see what I see there... look at frame 1944 and then 2769 guys
