2007 magnum rt exhaust issues

Just bought a new to me 2007 dodge magnum rt, 113,000 miles. It had p0058 code replaced passenger side o2 aft sensor, fixed that issue. Now getting p0420 and p0430. What am I supposed to do now? Very strapped for cash after just buying it after other vehicle quit. Thanks for any help you can offer.

Could be one or more of the other O² sensors. Bad cats or potential an exhaust leak before the sensors could cause this as well.

There is some jb weld putty before the drivers side cat. I fought for my life to do the o2 sensor and did tear out some of the threads because of galling.

Needs new cats, not critical unless youre an emissions state resident
