What is the tube connected to the catalytic converter for

I did a search but could not find anything. I am replacing the stock muffler and catalytic converter on my 86 with a B&B muffler. When I removed the old system there was a tube connected to the cat. My question is what is this tube for? I am guessing it has something to do with the air pump but not really sure. Also if I remove it how do I plug it up?
