Hello all, I'm curious to hear some opinions on how to go about doing this.

My 2004 RWD 4.0L came up with a dreaded P0430 code today after my "Check Engine" light came on. After taking it to the shop and looking at it myself, it looks like the bank 2 catalytic converter is beginning to fail. I made sure that the O2 and A/F sensors weren't the problem, so now I'm looking at replacing the converter. I've selected a decent aftermarket direct fit exhaust manifold from Davico after seeing some promising feedback on it, so now I'm entering the "Can I actually do this?" phase of the repair.

I'm just curious how doable this repair is at home? I've been looking through my repair manual (removal of front exhaust pipe/assembly), and, as always, things seem pretty straightforward on paper, but I anticipate there are some additional steps that need considering. I guess I'm just wondering if this repair is going to require me to raise or lower my engine, or anything to that extent? I'd like to think I'm pretty handy...but maybe not that handy.

Also, I'm aware that sometimes these catalytic converters involve welding and fitting, but I'm hoping to avoid that issue by going with a direct fit. I'm no welder, that's for sure.

Any advice or tips on doing this? Is it even possible for me to do this without moving my engine around?

It does not look to difficult. Just take your time, and be patient.
A few days before you tackle the job, start spraying all the bolts /nuts on the exhaust pipe and manifold with Liquid wrench or equivalent daily.
