How Many Catalytic Converters Are in a Tundra Pickup

A catalytic converter is a component that reduces pollution in your truck’s exhaust system. It is an important part of the truck to keep the environment clean. Your Toyota Tundra may have 2–5 catalytic converters installed, depending on the model year. As the catalytic converter is a critical component, it tends to be expensive.

Sometimes, the catalytic converter is stolen. In this article, I’ve covered the quantity and types of catalytic converters found in a Toyota Tundra, as well as their locations, costs to replace them, warning signs of failure, and significance.

What Is a Catalytic Converter?

A catalytic converter is an equipment that reduces hazardous chemicals in your truck’s exhaust. It is a portion of the exhaust, and it has a catalyst that increases the breakdown of chemicals without changing the gas.

Catalyst mixes with any contaminants in the exhaust gas when the gas moves via the converter, converting it into fewer hazardous compounds like carbon dioxide, water vapors, and gaseous nitrogen. The catalytic converter can enhance the atmosphere by effectively lowering pollutants.

Why Are Catalytic Converters Important?

Catalytic converters reduce hazardous chemicals in the exhaust gas of your truck. It removes chemicals such as carbon, hydrocarbons, and nitrogen from the gas to keep the environment clean. These substances have the potential to be as devastating as natural calamities like acid rain.

Therefore, to a considerable extent, the catalytic converter protects nature from the risk of catastrophic catastrophes by cleaning the exhaust gas. Thus, your truck’s catalytic converter is essential.

How Many Catalytic Converters Are in a Toyota Tundra?

The catalytic converter is one of the most important parts of the exhaust system. The Toyota Tundra has 2–5 catalytic converters depending on the truck’s model year.

I have made a chart here showing the model years and the number of catalytic converters:

The reason for increasing the catalytic converter in later models is to reduce exhaust gas pollution more than before. As a result, recent Tundra models can reduce exhaust gas pollution to a greater extent than before and keep the environment clean.

According to the individual model and grade level, the position of the catalytic converters may change in your Tundra. I always refer to the owner’s manual for the precise position of the catalytic converters on your truck.

Types of Catalytic Converter

Catalytic converters used in Toyota Tundras usually go into one of the following two categories:

1. Direct-Fit Catalytic Converter

Direct-fit catalytic converters have been manufactured especially for a particular kind and year of Tundra. However, direct fits are the priciest choice and most straightforward to install, offering the finest fit and efficiency.

2. Universal Catalytic Converter

Universal catalytic converters are not exclusive to any specific model of Tundra. Although universals can be less expensive than direct-fit converters, the type may need to be modified to be installed and may not offer the same degree of efficiency and fit.

Before installing new catalytic converters, you must match the perfect converter with your model year.

How to Maintain Catalytic Converter | 10 Maintenance Tips

Follow these 10 maintenance tips to maintain the catalytic converter in your truck:

  1. Change the engine oil frequently. Engine oil helps lubricate the rotating components and prevents overheating. Additionally, clean the engine regularly to protect the catalytic converter from dirt.
  2. Apply the proper fuel. The catalytic converter can be harmed by using the incorrect fuel. Use only the fuel that the manufacturer of your car has approved.
  3. Drive carefully if your air filter is filthy. A filthy air filter can restrict the engine’s airflow, which could lead to the catalytic converter overheating. Ensure that you replace your air filter as directed by the manufacturer.
  4. Don’t drive while the engine is misfiring. If you drive while the engine misfires, there is a risk of fuel entering the exhaust system, which can damage the catalytic converter. If the engine misfires, repair it as soon as possible without driving the truck.
  5. Drive carefully in rush-hour traffic. Traffic jams with frequent stops and starts may overheat the engine and harm the catalytic converter. If you must drive in rush hour traffic, try to maintain a reasonable engine rpm range.
  6. Drive cautiously in deep waters. Driving through deep water may cause the catalytic converter to become damaged if water enters the exhaust system.
  7. Don’t use exhaust cleaner. Exhaust cleaners may harm the catalytic converter. Use a non-caustic cleaner made especially for catalytic converters to clean your exhaust system.
  8. Inspect the catalytic converter regularly. A skilled mechanic can examine your catalytic converter for symptoms of damage.
  9. Thieves often steal catalytic converters, so park your truck in a safe place.
  10. Install a catalytic converter shield to protect your catalytic converter from theft and harm.

Symptoms of Catalytic Converter Failure

You will find the following 8 symptoms if the catalytic converter in your vehicle begins to fail:

  1. First, the most important symptom is that you will see the check engine light on the truck’s instrument cluster.
  2. A damaged catalytic converter blocks exhaust gas flow, reducing engine power.
  3. The truck will consume extra fuel.
  4. You will hear a loud noise from the exhaust system.
  5. At times, the exhaust system may overpressurize, causing the engine to overheat.
  6. You may smell a burnt smell from the catalytic converter.
  7. The engine may misfire due to a lack of sufficient oxygen.
  8. The catalytic converter may produce white smoke.

Tundra Catalytic Converter Replacement Cost

The cost of replacing a Toyota Tundra’s catalytic converter depends on the Tundra’s model year and your location. Generally, the total cost of replacing the catalytic converter in the USA for the Toyota Tundra is between $3500 and $4500, including the labor cost.

Also, the cost may vary depending on the model of the catalytic converter. If your truck’s catalytic converter is ever stolen, your insurance company may cover the replacement cost if you have full coverage on the instrument policy.

Why is My New Catalytic Converter Making Noise?

Sometimes, after you install a new catalytic converter, it may make noise. But what is the reason? What do you do then?

There are 4 reasons why a new catalytic converter is failing:

  1. When the metal cover of the new catalytic converter is loose, it makes a noise.
  2. When the inside of the catalytic converter is blocked, it makes a noise.
  3. When the catalytic converter is incorrectly installed.
  4. When the catalytic converter is damaged during the installation, it makes a noise.

If you hear a noise after installing a new catalytic converter, have a mechanic diagnose the cause and take the necessary steps to solve the issue.

How to Protect Your Catalytic Converter Toyota Tundra [9 Tips]

Catalytic converters are often stolen. You can follow these 9 tips to avoid theft:

  1. Try to park the truck in a place with adequate lighting. Thieves generally don’t target well-lit areas. Try parking in a garage or driveway. And if you must park outside, try to park where there are security cameras.
  2. Try using a security cage to protect the converter. You can buy it from auto parts shops or online.
  3. Use a motion-detecting alarm. A motion-detecting alarm can help discourage thieves.
  4. Seal the catalytic converter with your VIN number. It will be more challenging for thieves to market your catalytic converter as a result.
  5. You should brightly paint your catalytic converter so that thieves find it less appealing.
  6. Inspect your catalytic converter regularly. Inform the police right away if you see any modifications or damages.
  7. Observe your surroundings carefully. Be wary and call the police if you notice someone monitoring your truck.
  8. Purchase complete insurance. In the unlikely event of theft, full insurance will cover your catalytic converter replacement costs.
  9. If the converter is ever stolen, inform the police about the theft. This will assist in tracking down the issue and catching the thieves.


I hope you have understood the details about the catalytic converter. So, if your catalytic converter is damaged or stolen, take immediate action.

Also, be clear about your required insurance so that they can help you in time. Finally, let me know any questions you have regarding Toyota.
