Default Replace catalytic converter

I am looking for some advice on how to replace the catalytic converter on my 2003 Ion. I already purchased a direct-fit OEM Eastern catalytic converter online. My questions pertain to the removal process of the old converter:

I don't have access to a lift, so would it be easier to complete the job with the car on four stands?

What is the easiest way to remove the bolts/nuts (fasteners)?

Does anybody know the size of the bolts/nuts (fasteners) so I can purchase them before doing the repair?

Once the bolts are removed, is there some type of adhesion material that holds the flanges together or will it separate easily?

REWARD EXCELLENCE!

Put the front on jack stands. The easiest way to remove the bolts is to turn them (most of the time they turn better left to grrrrrr them off). No, I do not know the size. They cone apart pretty easy, but you will want new gaskets.

chances are the bolts are going to be rusted up. make sure you use some penatrating oil and let the bolts soak. if you are pacient you should be able to get them out.

if you happen to break one of the bolts the easiest thing to do would be to drill the bolt out and just use a bolt and nut to bolt things back together. at that point the bolt can be anything you want, suggest stainless, that fits in the drilled out hole. note it might take burning the old bolt out.

should need anything but new gaskets to install the cat.

Always replace bolts/nuts with this work.
