I have to replace my catalytic converter since I have a PO420 code. -I am just wondering what is the OEM for this Honda? also are all catalytic converters three-way or will regular direct fit work for a replacement? O2 sensors are good so that leaves the catalytic converters replacement.

Good evening,

The 420 is a catalytic converter failure.

You need to get a good quality catalytic converter. there are cheap ones out there but they will barely last a year.

You should consider a Walker, Bosal or the original equipment replacement.

I will attach some results for you to view.
