PO420 catalyst efficiency

I have an 01 Dakota with the 4.7, my check engine light keeps throwing this code, buddy of mine with an 01 R/T says the driver side converter is going bad cuz his did the same, If anyone has any experience with this please let me know, I'm trying to narrow it down, I've already replaced the upstream o2 sensor bout 3 weeks ago cuz it was throwing a heating circuit malfunction code, If the converter is going, Ima sell my superchips flashpaq, remove the y pipe, gut all 3 and get an sct tune and get the downstream o2's deleted like my friend did, but any info is appreciated

Sometimes an old post cat sensor will throw that code after the pre cat sensor has been changed. Change out the post cat sensor and see if this makes it go away.
