Question Replacing Catalytic Converter

After bring my 97' Jeep SE to the dealership due to terrible gas mileage I was told that my upstream and downstream O2 sensors are bad as well as my catalytic converter. The sensors are no problem but I was curious if anyone had any insight to replacing the catalytic. Is this a fairly easy process, does it require cutting and welding or is it a bolt on cat that I can simply replace? Thanks for your time!

When I had my cat replaced the guy cut out the old and welded in the new. I think there are bolt on kits but I'm not sure.

yes it will require cutting. There are bolt kits which i would not recommend. People still steal cats and your bolt kit will be even easier to take off since now you give them the space and on top of that make it easier to steal. Weld that sucker down.
