Honda Accord 2006 EX wont pass smog even though it passes emissions because catalytic car was sold with lacks a serial number. I was given a 2003 Honda Accords v6 catalytic converter as a replacement by a family member. Will this work if I install it to my 06? They are same generation Hondas.
Depends on the state. If you are in NY or CA the cat needs to be CARB certified and have an ID number that matches the CARB chart for that engine family and car fitment.
