Cat and 02 sensor

Cat and 02 sensor
So I have a bad cat on my 99 dakota. The material is ratteling around in there and it sounds like crap. I am gonna do the exhaust and replace everything including the cat if I can find a good price and I save for it. Right now I cant afford crap.
But to my question: so since the cat material is ratteling and loose I was thinking about just ramming a pipe through it to break as much free as possible, and then shake it out. Well then I was wondering how this would affect the rear o2 sensor? After all the cat is there to burn off the extra gas fumes and crap. So if I jam a pipe in there break it all free it will affect the mixture being read by the o2 sensor. So my question is how will it affect how the truck runs.
Will it A lean out the mix since it is sensing a rich mix since there is no cat
or b do nothing since the cat is shot
c something else
if it will lean out the mix is there an dummy o2 sensor that will trick the computer to thinking the 02 mix is fine?
I have been thinking about this the last week and havn't figures this one out.
