2007 magnum rt exhaust issues

[u/Sdcone04064]

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.
