How hard is it to replace the cat converter on a 2013 focus se?

Replaced both O2 sensors 8 maths back but I just started to get a P0420 error. Can I replace the cat myself in the garage? I normally do the brakes, suspension, ..., myself.

If you're doing brakes and suspension work, you probably are proficient enough. I would think the hard part is that you'd want the car up on a lift to have decent access. And the sensors associated will require a bit of wiring/electrical type work.

PF_Flyer, thanks.
I do as much of the auto work as I can to save money.
I think the biggest hurdle for this is having to lift the engine a few inches to extract the bad unit.
Cowlings, spacers, sub-frame bracket, sensors are all just tedious if carefully done.
Going to run another can of CataClean through to see if it resolves the issue.
Have a recall for a Canister Purge Valve replacement that will be done this month by dealership.
Possibly the cleaner and purge valve work will clear the distantly related codes.
Or a fall time cat replacement is in the future.
