Hello Scotty. I have a 2002 Subaru Forester with the check engine light on. I used a scanner and code came out to P0420. I changed out all O2 sensors but the code came back. Any help would be awesome. Thank you

It’s most likely the catalytic converter itself, if you already changed out the sensors.
