Anyone already did this and can give me some advice on how to do it? I'm pretty good at working on my truck. (Done a lot harder than this) but on the two front converts it almost looks impossible to undo the bolts on the engine side because the heat shield is in the way. But at the same time it looks crazy hard to try and get that heat shield off. It's hard enough to even see the bolts on the thing. Any advice on how yall did it would help! Thanks (2005 frontier 4.0)

I did mine a few months ago. I didn't have to cut any bolts or use a impact wrench. Make sure you soak all bolts with PB blaster in advance multiple times. This job requires patience and breaker bars. I replaced both front cats with walkers and denso o2 sensors. It's been 5k and so far so good.
