How to Tell Aftermarket Catalytic Converter

The best way to tell if a catalytic converter is aftermarket is by looking for a CARB (California Air Resources Board) sticker on the converter. If there is no sticker, it is likely that the converter is not legal in California. Aftermarket converters may also have different piping than stock converters, so you can also look for that if you are unsure.

  • Look for the catalytic converter’s EPA sticker
  • Aftermarket converters may not have this sticker, which is required by law in the United States
  • Inspect the appearance of the converter
  • Aftermarket converters may be made of lower quality materials and might not have a polished finish
  • Compare the price of the converter with that of similar models from other manufacturers
  • Aftermarket converters are often significantly cheaper than comparable OEM models

How to Tell Aftermarket Catalytic Converter


What is the Difference between an Original And Aftermarket Catalytic Converter?

An original catalytic converter is one that was installed on the vehicle when it was built. An aftermarket converter is one that is not made by the vehicle manufacturer and is installed after the vehicle leaves the factory. There are a few key differences between original and aftermarket converters.

The most important difference is in how they are designed to work with the engine. Original converters are designed specifically for each engine, while aftermarket converters are designed to work with a range of engines. This means that an aftermarket converter may not be as effective as an original converter, and it could even damage your engine if it’s not compatible.

It’s also important to note that aftermarket converters may not last as long as original converters. This is because they’re often made with lower-quality materials and don’t undergo the same rigorous testing as original converters. If you’re considering replacing your catalytic converter, it’s best to stick with an original converter from your vehicle manufacturer.

While it may cost more upfront, you’ll save money in the long run by avoiding potential engine damage and needing to replace your converter more frequently.

How Do I Tell What Kind of Catalytic Converter I Have?

If you’re looking to purchase a catalytic converter or if you need to have your current one replaced, it’s important to know what kind of converter you have. There are two main types of catalytic converters: oxidation converters and reduction converters. Here’s how you can tell which type you have:

An oxidation converter contains platinum and palladium. It works by oxidizing pollutants in the exhaust gas, such as carbon monoxide (CO) and hydrocarbons (HC). The reaction produces harmless products such as carbon dioxide (CO2) and water vapor (H2O).

A reduction converter contains rhodium. It works by reducing pollutants in the exhaust gas, such as nitrogen oxides (NOx). The reaction produces harmless products such as nitrogen (N2) and oxygen (O2).

To determine which type of catalytic converter you have, look for a stamped code on the side of the unit. The code will start with an “X” if it’s an oxidation converter, or an “R” if it’s a reduction converter.

Will Aftermarket Catalytic Converter Throw a Code?

If you’re considering installing an aftermarket catalytic converter on your vehicle, you might be wondering if it will throw a code. The answer is maybe. It depends on the type of aftermarket converter you install and how well it’s installed.

If you install a universal catalytic converter, it may not be compatible with your vehicle’s emission control system. This can cause your check engine light to come on, and you may get a trouble code from your onboard diagnostics (OBD) system. However, if you purchase an aftermarket catalytic converter that’s specifically designed for your make and model of vehicle, it shouldn’t throw a code.

But even then, a poor installation job could result in codes being thrown. So it’s always best to have any aftermarket catalytic converter professionally installed by a qualified mechanic.

Are Aftermarket Catalytic Converters Worth Anything?

When it comes to your car, you want to make sure that you are getting the most out of it. After all, you invested a lot of money into it and you want to ensure that it lasts for as long as possible. One way to do this is by installing an aftermarket catalytic converter.

But are aftermarket catalytic converters worth anything? The answer is yes! Aftermarket catalytic converters can actually improve the performance of your car.

They work by converting harmful emissions from your engine into harmless gases before they are released into the atmosphere. This helps to protect the environment and also improves the efficiency of your engine. In addition, aftermarket catalytic converters can also help to improve fuel economy.

So if you are looking for ways to get more out of your car, an aftermarket catalytic converter is definitely worth considering. Not only will it help to protect the environment, but it will also improve the performance and efficiency of your car.


If your vehicle failed an emissions test, or if you’re noticing a drop in fuel economy, it might be time to check your catalytic converter. In this blog post, we’ll show you how to tell if your catalytic converter needs to be replaced. First, let’s understand what a catalytic converter does.

It’s a device that helps convert harmful pollutants in exhaust gases into less harmful substances. A properly functioning converter is essential for keeping our air clean and our engines running efficiently. There are two main ways to tell if your catalytic converter needs to be replaced: by observing physical symptoms or by using an OBD II scanner.

Physical symptoms that may indicate a problem with the converter include: -A drop in engine performance -An increase in fuel consumption

-Black smoke coming from the exhaust pipe -A rattling noise coming from the engine bay If you suspect your catalytic converter is failing, the best way to confirm it is by using an OBD II scanner.

This tool will help you read any trouble codes that have been stored in the computer of your vehicle. If there is a problem with the converter, there will likely be a code related to it. Once you have this information, you can take your car to a mechanic for further diagnosis and repair.
