A modern Toyota Tundra can have up to four catalytic converters. Two of them are present on the front side in the hood between the exhaust system and muffler system, while the other two are located on the rear side underneath the car.
These catalytic converters are made of platinum, rhodium and palladium. They are very valuable and attract thieves.
1. Front catalytic converter
A catalytic converter is an essential piece of any vehicle’s exhaust system that converts airborne pollutants like carbon monoxide, hydrocarbons, and oxides of nitrogen into less harmful gasses. When a converter breaks down, your engine’s efficiency and fuel economy can go down.

There are two catalytic converters in a Tundra: one for the front and another for the rear. Fortunately, replacing a broken catalytic converter is a simple job.
To do this, you’ll need some basic tools and a good understanding of how your vehicle works. If you’re unsure of what you need, it may be a good idea to seek the help of an experienced mechanic.
If you’re not sure how to remove your catalytic converter, it may be best to get the assistance of a professional. A good mechanic will be able to guide you through the process and ensure that your converter is properly connected. It’s also important to take your time when removing the converter to make sure that you don’t accidentally break the connection.
2. Rear catalytic converter
A catalytic converter is a component of the exhaust system that converts CO, HC and NOx into less harmful gasses. This process helps to keep the environment clean, reduce emissions and improve fuel economy.
The Toyota Tundra is a full-size pickup truck that comes in six trims. Each one is powered by a 4.6-liter V8 engine with 310 horsepower and 327 pound-feet of torque.
This vehicle is also available in a 5.7-liter V8 engine that offers up 381 horsepower and 401 pound-feet of torque. The Tundra is a popular choice for people in Milroy, Anderson and Penn State because it provides ample power with excellent fuel efficiency and a reliable ride.
The Tundra is a bit behind the competition in terms of in-vehicle technology, but it’s still a class-competitor when it comes to safety features. The Tundra’s Toyota Safety Sense P (TSS-P) package includes lane-departure warning, forward-collision warning, automatic emergency braking, adaptive cruise control and automatic high-beam headlights.
3. Tagging
Catalytic converters are a popular target for thieves as they’re easily accessible and can be cut within 30 seconds with a battery-powered saw.

There are four catalytic converters in a 2019 Toyota Tundra, two in the front near the engine manifold and two in the back near the mufflers. The first-generation models have two, while later ones contain four.
The tagging of catalytic converters helps law enforcement track them when they’re stolen, according to the National Insurance Crime Bureau. The tagging is done on the converter’s surface with a special acid that etches a serial number into the converter.
Several parts dealers have joined forces to stop catalytic converter thefts in their tracks, including Midas and Napa Auto Parts. They are offering to etch catalytic converters for free, which could help police and salvage yards locate them in the event they’re stolen.
4. Anti-theft shield
One of the best ways to protect your catalytic converters from theft is by using an anti-theft shield. These metal plates are fastened over the converters and are designed to make it impossible for thieves to remove them.
There are many different types of catalytic converter shields on the market, but they are usually manufactured to fit specific cars and trucks. Some of these shields are made specifically for Toyota Tundras and Sequoias, while others are marketed for certain models like 2WD and 4WD Tundras and those with TRD skid plates.
Most of these catalytic converter shields will prevent thieves from taking the catalytic converters, but it doesn’t always mean they won’t try to steal your truck. Ideally, you should park your truck in a garage or secure parking lot where it will be difficult for thieves to steal it.
