Default Catalytic question!!!!

just put a new set of injectors in and realized my catalytic converters were clogged. i have 4 all together two in the front right after the exhaust manifolds and 2 in the rear. i believe it's the 2 in the front that are clogged since those are the most common ones that get clogged. Because of this i have lost a majority of the power. As i did some research i learned that the front piece that has the first two cats was for the california emission standards. I'm not sure if this piece is a factory piece and that all rangers come with them and if a necessity or if i have the option of putting a replacement peice with out the two cats. Please help me out asap because i am trying to get my truck running right in order to sell it for another vehicle. thank you

I'm not helping if you are selling the

Change the Cats out for another cat, they make aftermarket ones that are cheaper, but in all honesty put stock ones back on. Any good exhaust shop can take them off easily enough and tell you what you need, whether it is the front cats or the back ones. As for it being a factory piece, I'm sure it has a Ford marking on it, and if you haven't touched the truck to modify the engine or exhaust, and the previous owner didn't either, they are probably stock
