A catalytic converter is a crucial component of a vehicle’s emissions control system. It looks like a muffler but is actually a stainless steel housing with a ceramic honeycomb that contains catalyst particles such as platinum, palladium and rhodium.

The catalyst particles superheat unburned hydrocarbons in the exhaust gases, breaking them down into less harmful emissions before they leave your car’s tailpipe. This reduces the amount of toxic fumes you emit while driving and improves your car’s smog rating.

Unfortunately, despite all of the advancements that have been made in the way we store our cars, it is still a common practice for thieves to steal catalytic converters. So, you have to be prepared for this eventuality and do whatever it takes to keep your converters safe.


When you need to replace your Toyota Tundra catalytic converter, make sure that the replacement comes from a reputable supplier. A bad converter can lead to a loss of power and a foul odor that you can’t get rid of.

You’ll also want to use a high-quality replacement converter that was made by the same manufacturer as your original unit. These are often available as direct-fit units that don’t need to be welded or clamped in place.

Another way to protect your catalytic converter is by installing a cat shield. These can be purchased in several different styles and are custom-fit for your truck.

While these solutions won’t 100% prevent your catalytic converters from being stolen, they can drastically reduce your chances of having them taken off your vehicle. They’re easy to install and will help keep thieves away from your truck. Many of them come with a deterrent feature that alerts you if someone is trying to break into your car.


Catalytic converters are responsible for reducing the harmful gases like carbon monoxide, hydrocarbons and nitrogen oxides that exit your vehicle’s exhaust. They use precious metals to trigger chemical reactions that change these toxic molecules into less toxic substances, like oxygen and nitrogen gas.

If you’re a Toyota owner, you know that quality maintenance goes a long way. Whether you’re getting your Tundra to work on time or going on an exciting adventure, nothing beats installing high-quality parts.

If your Toyota Tundra catalytic converter is on its way out, it’s a good idea to replace it. This will allow you to enjoy improved fuel efficiency and prevent the rotten egg smell.

The first thing you need to do is determine which type of replacement converter is right for your vehicle. This can be done by consulting the Walker CalCat catalog, which lists specific converters for each vehicle model.

The next step is to make sure the new converter fits into the OE location and will not cause an OBD catalyst code. You can do this by looking for the Emissions Control Information Label, which is located in the engine compartment and should be easily accessible.
