Smog pump just pumps air (oxygen) to the cats to light them up/make them run hotter faster to cut down on smog. Im not sure this post is really conclusive that no air pump kills cats

Did those cars come stock with smog pumps and you took them off? If so then I could agree with your point, but I THINK (not 100% if I'm wrong forgive me lol!) these cars rely on the smog pump to light the cat off. Kinda like stoking a fire with one of those bellows. If the cat doesn't get hot enough to light off its gonna soot up. I think those newer cars are able to adjust the a/f ratio to replace the actual pump.
