I’ve picked up a p0432 code, catalytic converter not working at full efficiency. Is there an easy way to get rid of this?

I was also wondering which of the three cats is causing this issue, as far as I can tell, there’s 3 and I don’t know how to identify them.

If I were to “allegedly” clear the honeycomb out of the cat, would this fix the issue? Is there a way to get the light to go away after doing this?

I know when I did my tummy tuck,I completely eliminated the third cat,it is an unmonitored cleanup cat so no light there.makes the passenger floor much cooler.so it would have to be one of two mini cats .maybe someone will chime in on which one?

Thanks for the response, I’ll likely eliminate the third cat while I’m under there regardless as preventative maintenance, as far as which cat it is, I would love to find out. Any ideas on how to trick the sensors to eliminate the check engine light?

Yes and it’s all bolt in (you will have to cut and reuse the ends of the cat)just get a pipe from O’Reilly and weld the bolt on ends,I coated my finished pipe with vht paint.
I think they only need to see a different signal top from bottom,you might try a nonfowler to space it some.but I would really want to remove the upper 02,s and get a look at them with a camera,it’s easy to do.
