Checked out my CEL and found P0430, P0455, P0441 so I did some digging at my exhaust and found the leak coming out of these two spots. Whole thing is very rusted, don’t believe it’s the headers or the cats but just these two. Do I just replace these or get the Burt man cat back

0430 is your down stream o2 sensor and 0455 (large leak) and 0441 both have to do with your EVAP system, not your exhaust piping. Find where you have a leak in your evap system and fix that first. Then clear the codes. If 0430 gets throw again but the other 2 codes are not throw, it’s time for a new downstream o2 sensor as well.
First thing you should do is confirm your gas cap is sealed correctly.
