The P0420 code came on the other day, and after clearing the code it's come back again. Has 199k so probably is the catalytic converter. Does an oem one have to be used or will an aftermarket one perform/ last as long as an oem? Thanks.

Add a bottle of Seafoam to a full gas tank and see if it comes back. Could buy you some time to save up $$.
Every 3 months I add a bottle to keep the cat happy.
Worked for me.
