do they make direct fit bolt on cats or would i have to cut n weld a new one in?

i have recently replaced plugs and wires in last 12k.

it has a terrible rattle from underneath sounds like loose cat pieces probably. wat does the average cat cost and skill level to replace? and could it be a combination of MAF and bad CAT/ O2 sensor? i dunno im not the greatest diagnoser but i can hang parts pretty well

its been unplugged for a while and still runs like *shoot*. suspicious of a dead cyl. or bad valve component. just feels very stumbly and choked but THEE only dtc is a MAF sensor
