Theft Prevention for Catalytic Converters

There has recently been an increase in the theft of catalytic converters throughout the Dyfed Powys Force Area.

The following information may assist you in keeping your vehicles safe from this type of theft.

Exhaust system

The catalytic converter is an emission-controlling device that is a part of the exhaust system of many automobiles and trucks. It uses a platinum-iridium catalyst to oxidize pollutants before they can be released into the air, and it converts carbon monoxide into carbon dioxide. The platinum on the converter makes it a valuable device and theft is a common concern. Protecting your catalytic converter from theft needs to be a priority.

Protecting the Car

A thief can’t get to your catalytic converter if he can’t get to your car. Keep your car stored in a garage if you have one available. If not, park in well-lit areas at night or secured driveways. If your car is isolated, it makes it easier for a thief to crawl under the car and saw the converter off, which can be done in seconds. Avoid parking too close to stairwells in parking garages since these make for easy escape routes for thieves.

Securing the Converter

Some converters are only attached to the car exhaust using bolts, and this can make them even easier to remove. Some vehicles are more susceptible to this than others. Consider getting the bolts spot welded which secures the converter in place to make it more difficult for a thief to remove. Alarm devices, which are sensitive to vibration, can also be secured to the undercarriage of the car.

When the car vibrates as the converter is being removed, the alarm goes off. A sensor can also be triggered if an unauthorized person slides under the vehicle. There are other convertor protectors available which are freely advertised on the internet and in trade magazines. These lock in around the converter to make it more difficult to remove. It takes more time and effort than most thieves will have.

Additional Tips

If you are a business user and have multiple vehicles, use your vehicle that has the lowest clearance underneath to block the vehicle with the higher clearance. 4×4’s and vans are popular targets because the chassis are higher up and the thief can slide under the vehicle easier. Blocking that access with a lower-riding car makes that more difficult.

If its easier, consider allowing your staff to take vehicles home in the evening, better than leaving them in a vulnerable place. Install additional security lighting in your driveway or around your business. Consider CCTV that covers the vehicles when parked.

When replacing a converter, ask the installer to etch / engrave your registration number onto the cat. One way of recovering a stolen converter is to etch a serial number on it. It won’t prevent theft, but you can report the number to police if it does get stolen and they can trace it through local metal buyers.
