Is My Catalytic Converter an OEM?

We are regularly asked if my Catalytic Converter OEM. We have a few things to look for when you identify your catalytic converter and if it’s an OEM.

What Does OEM Catalytic Converter Mean?

Before we give tips on identifying an OEM cat, it’s essential to know what “OEM” means. “OEM” stands for “Original Equipment Manufacturer.”

This means the catalytic converter that was initially put on the vehicle, or if it was replaced, was replaced with the genuine catalytic converter from that original manufacturer. While getting an OEM replacement catalytic converter may make sense, most people do NOT do that because it can be a very costly repair compared to an aftermarket catalytic converter installation.

Why are OEM Catalytic Converters More Expensive?

The main reason OEM Cats are worth more is the number of precious metals found inside (Platinum, Palladium, Rhodium). The vehicle manufacturers use more of these precious metals instead of the less-expensive alternative aftermarket cats. So that’s why when you replace broken catalytic converters, there is a massive difference in price from an OEM to an aftermarket cat.

How To Identify An OEM Cat

Two Ways To Identify If You Have an OEM Cataly, tic Converter

Look for a Manufacthe manufacturer’s stamp, a logo, specific words for the brand, or pattern of serial numbers.

The Welds will be Cleaner – When you are looking at the welds along with an OEM catalytic converter, the edges of the welds along the cat will be cleaner and less-messy looking.

When trying to tell if you have an OEM Catalytic Converter the first thing to look for is a stamp of the manufacturer. Typically, they are by the serial number. It will be the name (Ex: FoMoCo – Ford Motor Company, Land Rover, Hyundai / Kia) or the manufacturer’s emblem (Common for Toyota Catalytic Converters – below).

OEM cats welds will be cleaner because they were produced by the manufacturer and installed on the car during the build. Most aftermarkets have messy welds because they are installed by a repair shop and getting it on is more important than how the welds look.

Many OEM units will have the manufacturer’s logo or full name spelled out on the cat. This helps you to know that it was not an aftermarket unit, and if you do not know what type of car it came off of, this will help as well. Many teams will help you see what makes it come off of, which will help you determine if it is OEM or not.
