I have a 2014 Nissan Pathfinder Platinum, and it has codes P0420/0430, which have been there for a few months. I need to replace the front right and left catalytic converters, does anyone know anything about doing this yourself. The fit up looks very straight forward, but I’m not sure what it will take to get to the connection with the exhaust manifold, which I’m sure is a bear!

Once you get eyes on the mounting hardware and depending on its condition.
At best you’ll just need sockets and a ratchet for removal
At worst, lot of penetrating oil, a torch, air hammer and chisel, grinder and cut off wheels etc.Might need that special socket for one of the o2 sensors (slot for the wire), wouldn’t hurt to have that ahead of time
