Stop Catalytic Converter Theft On Toyota Prius With This New Protective Shield

If you have not heard about the string catalytic converter thefts on Toyota Prius cars, trust me, it is real. Here is how one company is fighting back against the thieves.

If someone had asked me what was so valuable about a Toyota Prius, I sure would not have answered catalytic converter. I would have thought more along the lines of the $1500 to $3000 hybrid battery.

However, thieves have found that catalytic converters on Toyota Prius are easy money. If you have been a victim of this crime, here is what you can do to prevent it from happening again.

What Is A Catalytic Converter
A catalytic converter is a device that takes harmful exhaust gasses and passes them through precious metals. This process cleans up the exhaust and allows us to have cleaner air. They are critical, especially for the Prius, which is a low emission vehicle.

The unit on Prius, comprising of 2 converters, can weigh in at a hefty $1500 or more depending on where you live. In California, due to CARB regulations (California Air Resources Board), you have one option only. The dealer. Other states, such as Florida and New York, have similar laws.

According to Cap City Muffler in Sacramento, California "The dealerships' list price on this converter is $2148, and by the time you replace the hardware that needs to be installed, the front gasket, the 02 sensors, and labor of the installation, you are at roughly $2500.00."

Aftermarket catalytic converters are typically less densely packed. While they carry the same precious metals in them, there can be varying amounts of these metals, which can be the deciding factor in how much the converters cost. There are some cheaper options out there but are typically not recommended as they do not last like the OEM converters.

Why Do Thieves Want Them
Thieves want these converters and especially the OEM ones. There are higher levels of these precious metals in them, which, when they get scrapped, can give the thief anywhere from $375 to $850 or more per converter. The precious metals, platinum, palladium, and rhodium. These metals can be made into jewelry and be protective coatings also.

These metals are the reason that thieves want them, and they want the OEM ones. OEM converters are more substantial and carry more dense levels of the metals. Toyota Prius has tightly packed catalytic converters because it is trying to achieve very low tailpipe emissions. So it makes sense for thieves to target the Prius. The converters on them will bring the highest scrap value.

If a pair of "cat thieves" can snag a few of these every day, that can add up to thousands a week. The business can be quite lucrative. Your Toyota Prius is worth more than you think.

What Can Be Done To Protect My Prius
It can take thieves less than three minutes to steal one of these high-cost converters. That is not very long, and most of the thieves make a clean getaway. This puts Prius owners in serious jeopardy.

There used to be no real way to keep thieves from stealing these until now. Enter Cat Security™, a robust aluminum plate that, once installed, provides a strong barrier against catalytic converter theft. Developed by two muffler shop partners in Sacramento, California, this team aims to stop a robbery and provide its customers with peace of mind.

The product is more than just an anti-theft plate, though, it has some other benefits. It is straightforward to install, requiring no welding. It uses the factory studs and comfortably aligns with your Prius undercarriage. Special fasteners also help as a theft deterrent, keeping unwanted hands out of your car. The shield also may help with the aerodynamics of your Prius, as well. The guard could translate into increased fuel economy, though there is no data to support this currently.

Getting A Cat Security Plate For Your Prius
Cap City Muffler in Sacramento California would be happy to install one of these on your Toyota Prius for around $225. The shield is a whole lot cheaper than replacing a $2500 catalytic converter.

Looks great but what happens when the smog test is performed? Do I have to remove the plate? Thanks.
There will be an open spot to allow for viewing on the production model to accommodate.
How are the thieves immune to this aluminum plate? For 3-4 minutes more they will also made off with the $200 aluminium piece for recycling.
The estimated time to remove the plate by a professional shop is 15 to 20 minutes with the appropriate power tools and a lift. The two different types of security fasteners make it a challenge. If you wanted to use a single tool to remove the shield I could only see a grinder removing them both successfully. if the noise from using a grinder isn’t a big enough deterrent to a thief then Im sure one can imagine how long it would take to lay on your back under a car and grind down 14 security fasteners and still have bolts left to deal with on the front of the shield. I don’t see this happening in 3 or 4 minutes. The risk of getting injured from the grinder and added risk to getting caught for the amount of time spent under the vehicle I think would be a huge deterrent to any thief. Like any anti-theft device. they are all deterrents and are in installed to put a thief at a higher risk of being caught. I personally think that thieves would simply move on to another car without a security device in place as the extra risk could be avoided. Another thing to note is thieves are using basic tools (chain tubing cutter, pair of wire cutters and a socket for bolts) the odds of the theives having a grinder with them to remove the plate is highly unlikely
