https://catalyticcontrol.rockawayrecy... - In this video, Tom explains some places you may find a serial number on a catalytic converter especially if it has a shield on it. You may have the ability to easily peel back the shield to get access to the number, but you may not too. So be sure to check the entire cat for a serial number and if you can't find one you can always send pictures to RRcats.com for a quote.
