Protect Your Vehicle’s Catalytic Converter
Catalytic converters reduce emissions and help your vehicle run smoothly by filtering out harmful byproducts in exhaust gases and burning them up. They’re an incredibly important part of your car and no one knows that more than would-be thieves.
Since 1975, catalytic converters have been mandated in American vehicles and they’ve been a popular target for thieves ever since due to the valuable metals they contain. So, protecting your vehicle from catalytic converter theft is the prudent thing to do.
Catalytic Converter Shields from ADD Automotive
Here at ADD Automotive, we’ve been in the business of protecting catalytic converters for more than 30 years. We manufacture and sell corrosion-resistant, durable catalytic converter shields. Our fully custom-designed product will not void your vehicle’s warranty and does not require any parts modification for installation. We also provide fully custom, American-made bolt fasteners when you purchase a shield.
The shields are available in certain brands of Toyota, Lexus, Ford, Chevy, V-8 Ram, GMC, and Isuzu. They weigh 11 pounds and are made of a high-grade aluminum that works to both dissipate heat and resist corrosion. The shield can end up paying for itself in the long term, as it can get you a discount on your monthly car insurance rate. And in three decades of business, no thief has been able to get through our shields to steal our customer’s converter.

Just place the adhesive rubber bumper in a suitable location and tighten the security bolts. Ensure that the shield doesn’t collide with the frame and your car will be ready to go!
