Protect Your 2021 Toyota Tundra From Catalytic Converter Theft

The 2021 Toyota Tundra has become a prime target for catalytic converter theft due to its easy access and quick cutout time.

One way to prevent theft is installing a catalytic converter shield. These are similar to locks in that they will slow down thieves but won’t completely stop them.

Product Description

A catalytic converter is a device that transforms exhaust gases produced by your vehicle’s engine into less hazardous emissions. It consists of a stainless steel housing filled with platinum, palladium and rhodium for increased corrosion resistance.

These precious metals are used in 2021 Toyota Tundra catalytic converters to reduce vehicle exhaust emissions and boost fuel economy – but they also hold considerable value to thieves.

Fortunately, there are a few steps you can take to protect your catalytic converter from theft. One of these is parking your truck in an isolated and secure area.

Another solution is installing a physical anti-theft shield around your catalytic converter. These devices create an impenetrable wire cage around the converter, making it hard to cut away at data.

MillerCAT offers a selection of catalytic converter protection shields that fit various vehicles. Each shield features tamperproof security hardware at every mounting point, so thieves cannot use standard bolts to attach the device.

Installation Instructions

Toyota Tundras feature four catalytic converters, two at the front and two in the rear near the mufflers. Each of these can fetch high prices on the black market, so Tundra owners must safeguard theirs from theft.

The Tundra is a prime target for catalytic converter thieves due to its high ground clearance, which allows them to easily slide under the vehicle and access the catalytic converters.

Catalytic converter thieves can quickly cut one out with a battery-operated saw, so it’s critical to install an anti-theft shield on your Tundra for protection against theft.

For the 2021 Toyota Tundra, there are several options for security plates and catalytic converter covers. While some of these solutions can be cost-effective alternatives to replacing all four converters, which one is best for you depends on your individual needs and preferences.


Even with Toyota’s legendary reliability, unexpected repairs and maintenance issues do arise occasionally. That’s why many drivers opt to purchase an extended warranty that covers repairs beyond the standard manufacturer warranty period.

To learn more about what warranties are offered, it’s essential to read your vehicle owner’s manual. These documents can be found online or at your nearest Toyota dealer.

Toyota’s basic warranty program covers engine and transmission components for six years or 60,000 miles, whichever occurs first. It also extends coverage to various bearings, seals, gaskets, joints, shafts, mounts and associated electronics during this same period.

Hybrid powertrain components and the battery are covered for eight years or 100,000 miles, whichever comes first. For 2020 and newer hybrid models, however, this protection has been increased to 10 years or 150,000 miles.

Toyota also provides an Accessories Warranty for official Toyota accessories that are installed during purchase. These parts are covered for one year from date of installation or the remainder of your new car warranty if applicable.
