There's a mod involving two spark plug defoulers you can do to trick the ECU into getting an acceptable reading from the secondary sensor. Take first defouler, drill through it. screw the 02 sensor into that, then screw those into the 2nd defouler, and that into the exhaust.

actually here is a link. need to do this to mine so I have it bookmarked. everything is running fine so I just want to shut the light off. don't want to miss any other codes that might show up.

A bad cat will almost always throw code P0420.
