And since every gasoline-driven car has a catalytic converter, thieves only need to stroll down the street or into a parking garage to find their targets.
Fortunately, they're unlikely to choose your sedan. In this article, we’ll show you how to prevent catalytic converter theft in a 2021 Toyota Corolla. You'll learn where your car's “cats” are located, how to protect them, and what kind of
car insurance

Is it easy to steal the catalytic converter from a 2021 Toyota Corolla? 

No, it’s not easy to steal a catalytic converter from a 2021 Toyota Corolla.
The '21 Corolla has two catalytic converters in its engine compartment, both of which are under the hood. To open a Corolla’s hood, a would-be thief would first have to break into the cabin and flip the release switch to the left of the steering wheel.
Next, they’d have to dismantle several parts to get their prize, including the integrated exhaust manifolds that bolt the cat cons to the engine.
Pick-up trucks and SUVs are the most common targets for thieves. Their catalytic converters are integrated with the exhaust pipes on the underside of the car and are completely unprotected. You can also wiggle under them pretty easily. A burglar with a saw can get away with a cat con in about one minute thanks to the

of almost 11 inches.

Catalytic converters are valuable because they contain precious metals, such as rhodium, platinum, and palladium. These metals are used to filter toxic chemicals from your car's exhaust, reduce harmful emissions, and improve air quality. They also go for a pretty penny on the black market, making them an attractive target for thieves.
Catalytic converters are also a huge pain to replace!

Install an anti-theft alarm

A car alarm is the best

in this situation. While the Corolla contains its own security system, it doesn't hurt to add an extra layer of protection that thieves won't expect. You might even receive a car insurance discount for making your vehicle that much safer.

Etch your VIN on the catalytic converter

Etching your Corolla's

onto the catalytic converters makes them easier to track and almost impossible to sell. You want the etching to be visible so that a thief can spot it before they dismantle your engine. It's another way to tell burglars that your sedan isn’t worth their time.

What to do if your 2021 Toyota Corolla’s catalytic converters are stolen

If you discover that one or both of your Corolla's catalytic converters have been stolen, you should first call the police, followed by a towing company, and lastly, your insurance provider.

How do you know if your car is missing a catalytic converter?

As your Corolla's catalytic converters are inside the engine compartment, the first thing you'll probably notice is that the hood isn't closed properly or that the driver door is unlocked.
Even if the thieves cleaned up after themselves, a missing cat con is impossible to conceal once you start up the engine.
Here’s what you’ll notice:
  • An engine that’s much louder than normal
  • Decreased gas mileage
  • Hesitation during acceleration
If the worst has happened, step out of your car and grab your phone.

Call the police

It's best to contact the police as soon as you notice that your car has been tampered with. The sooner they can examine your car and any security footage from nearby cameras, the better their chances of recovering your missing part(s). Take pictures of the parking location, note any damage to your car, and call for a tow while you're waiting.

Call for a tow

Can you drive your Corolla without either of its catalytic converters? Maybe, but it’s not worth the risk. To access the parts, the thief would have had to rummage around in your engine compartment, and they probably left loose parts and bolts behind.
Driving your car—even if it’s just to the nearest garage—could cause enough engine damage to make you wish you’d simply paid the

.

File a car insurance claim

Regardless of whether the police catch the culprits, the officer at the scene will file a police report. You can usually request a copy online about a week after the incident. Include the report, your pictures, and any notes when you file a car insurance claim.
