A vehicle’s catalytic converter plays a key role in reducing pollutants emitted by a vehicle’s engine. By breaking down and converting harmful emissions, the catalytic converter helps keep the environment clean.
The catalytic converter is an essential component of a vehicle’s emission control system. It is responsible for reducing harmful pollutants emitted by the engine, such as carbon monoxide, hydrocarbons, and oxides of nitrogen. By breaking down these emissions, the catalytic converter helps to keep the environment clean.
In this article, we will help you find the right catalytic converter for your vehicle. We’ll also provide some tips on how to properly maintain your converter to keep it working efficiently.
How To Buy A Catalytic Converter
If it’s your first time buying a catalytic converter, it can become confusing. Even mechanics still make mistakes sometimes if they’re not mindful of what they’re buying. Furthermore, buying the wrong type of catalytic converter could risk violating federal or state regulations.
In this article, you’ll see advice on how to buy the correct catalytic converter. This way, you’ll be sure you meet your state’s regulations. At the end of the article, you’ll also find a list of catalytic converters available online as suggestions.
What Is A Catalytic Converter?
Catalytic converters (also known as “cat cons” or “cats) are parts of the exhaust system. They help convert the emitted toxic gases into harmless gases. What’s more, inside this device, the “catalyst” part is where the chemical reaction takes place.
There are two types of catalysts depending on what chemical reaction takes place.
Two-way catalyst
Diesel engines mainly use two-way catalytic converters, which reduce the emissions of carbon monoxide and hydrocarbons. They also perform two simultaneous functions: oxidize hydrocarbons and convert them to water and carbon dioxide, and oxidize carbon monoxide to carbon dioxide.
Three-way catalyst
You will find three-way catalytic converters in lighter-duty vehicles, particularly those with gasoline-powered engines. Compared to two-way converters, three-way converters also control the emission of nitrous oxide.
As the name implies, three-way converters perform three functions: it reduces nitrogen oxide to oxygen and nitrogen, oxidizes hydrocarbons to water and carbon dioxide, and oxidize carbon monoxide to carbon dioxide.
Catalytic converters are mainly built to control toxic emissions coming from vehicles, which is why these devices are highly regulated both at the state and federal levels.
California Emissions/Federal Emissions
In California, the aftermarket of catalytic converters became strictly regulated after the California Air Resources Board (CARB) created regulations for it in 2009. This means anyone purchasing a catalytic converter within the state of California must abide by the regulations set by the CARB.
To help you with your purchasing decision, here are 4 simple steps:
1. Application
Make sure to note down the year you purchased your vehicle, as well as its make and model.
2. Emissions Level
Look for the Vehicle Emissions Control Information Tag located in both under the hood and near the radiator. You can spot these easily.
3. Converter Grade
If you’re not sure about which converter grade your car should have, you can simply consult your mechanic to check this for you.
4. Converter Configuration
Direct-fit configurations mean that the converter can be fitted directly without the need for any modification. This is best used for vehicles that still have the original factory exhaust systems.
Universal-fit configurations will need some welding or fabrications done to fit it to a vehicle. This is the more cost-effective option.
Some Recommendations
Below are three of the most recommended catalytic converters that are compliant with the CARB regulations.
Walker 81767 Calcat OBDII Catalytic Converter
This converter’s stainless steel body is even more durable due to its heat shields and aluminized pipes. In addition, its OE-style hanger position and routing make it easy to install. Also, it has OE-style brackets, hangers, and flanges for improved strength.
Customers who’ve tried it said their vehicles ran more smoothly and their exhausts smelled cleaner after installing it.
On the other hand, the only downside to this is that it doesn’t come with an installation kit. Hence, you’ll have to make use of your previous nuts and assemblies.
Price: $254 – $480
Eastern 50366 Direct Fit Catalytic Converter
This Eastern direct-fit converter has a high-flow design and catalytic chemistry. It focuses on maximizing catalytic efficiency and engine output. If you purchase this converter it will include a Value Pack installation kit. Furthermore, this kit contains everything needed for an easy and fast installation, including gaskets, studs, fasteners, and other accessories.
According to reviews, you can use these in SUVs and light trucks that accommodate OE-style assemblies. This is also a great choice for DIY people. This is because it already comes with an installation kit.
Price: $275 – $480
Walker 16387 Direct Fit Catalytic Converter
This one is specifically for OBDII vehicles. Also, it still carries a stainless body, and its durability remains superb. This is due to the heat shields and aluminized pipes. It uses OE-style hangers, flanges, and brackets.
Looking at the reviews, this converter fits well into most vehicles. However, it doesn’t come with gaskets. Hence, make sure to buy the correctly sized ones from Walker (in sizes #31619 and #31383).
Price: $133 – $260
These three converters have great reviews on Amazon. However, consult with your mechanic to see if they have other recommended converters for your vehicle.
How Long Do Catalytic Converters Last?
The lifespan of your catalytic converter will depend on how you drive and maintain your car. If you’re constantly driving in stop-and-go traffic, this will cause the converter to overheat and degrade faster.
On the other hand, if you take care of your car and maintain it well, your converter can last up to 10 years or more.
In any case, it’s always best to check your converter every now and then. This is to make sure it’s still functioning properly. If you notice any drop in performance, have it checked as soon as possible.
Can I Remove My Catalytic Converter?
Some car enthusiasts who are looking for more horsepower might be tempted to remove their catalytic converter. This is because it can add weight and restrict airflow. However, this isn’t advisable as it’s illegal in most states.
Not to mention, removing your catalytic converter will also cause your car to fail its emissions test.
Catalytic converters are an important part of any car. They help to reduce emissions and make your car more environmentally friendly. When choosing a catalytic converter, it’s important to consult with your mechanic to find the best one for your car.
How Do I Know My Catalytic Converter is Bad?
There are some warning signs that your catalytic converter might be going bad. These include:
- Your car is having trouble starting.
- You notice a decrease in fuel economy.
- Your car is running rougher than usual.
- There’s an increase in exhaust fumes.
- You hear rattling or buzzing coming from the engine area.
If you notice any of these warning signs, it’s important to take your car to a mechanic so they can diagnose the problem. In some cases, the catalytic converter can be repaired. However, in other cases, it will need to be replaced.
Due to the cost of a catalytic converter, it’s important to be sure that it’s actually the problem. There are a few other things that can cause similar symptoms. These include:
- A faulty oxygen sensor
- A clogged air filter
- A leaking exhaust manifold
If your mechanic finds that your catalytic converter is bad they will be able to give you replacement options.

Why Do Catalytic Converters Get Stolen?
Considering that most cars now have catalytic converters, it’s no wonder that they’re being stolen more frequently.
After all, they contain valuable metals like palladium and platinum. But why do criminals target catalytic converters specifically?
There are a few reasons. First, they’re relatively easy to remove. All a thief needs is a saw or a wrench, and they can be detached in a matter of minutes.
Second, catalytic converters are often located in areas that are easy to access, such as under the car. This makes them ideal targets for thieves looking for a quick score.
Third, the metals inside catalytic converters are quite valuable. Palladium, for example, can fetch up to $2,500 per ounce on the open market.
It’s not a bad idea to get a dash camera or a security system on your car. This will help prevent your car from being a victim to criminals.
