I have taken all the nuts off and disconnected all the sensors. Everything is loose but where the catalytic assembly connects to the passenger side
exaust. I noticed that two of the nuts on this side where 14mm all the rest are 15mm. What is the secret to getting it to break free?

Thanks

If you cant budge em, cut them off with a torch, or sawzall with a metal blade, and use new ones...the nuts may have just rusted down to that size!
