Well after my car contiuously throwing a P0420 and a significant power loss, Ive come to the conclusion that i need a new cat, now the question that i have is what will happen to the downstream 02 sensor if you get an aftermarket cat bc I cant seem to find a replacement for under $250 so I noticed that a lot of the aftermarkets dont have a hole on the cat for the downstream.

You can have a bung for the O2 welded in. The bung itself is only a couple bucks from places like Summit, or your exhaust shop might have them.

if you want an aftermarket cat, you should check out performance-curve.com. i got this cat with an O2 bung already in it. its been on about 2 years and its still working great.
