ADD A CAT Catalytic Converter Shield FAQs

Have questions about catalytic converter theft protection? Below are answers to common questions about ADD A CAT Catalytic Converter Shields, installation, materials, security hardware, fitment and warranty.

What is an ADD A CAT Catalytic Converter Shield?

An ADD A CAT Catalytic Converter Shield is a vehicle-specific physical barrier designed to make a catalytic converter more difficult and time-consuming to access. ADD A CAT shields are manufactured for compatible Toyota, Lexus, Ford, Ram, Chevrolet, GMC and Isuzu applications.

Do catalytic converter shields really work?

A catalytic converter shield adds a physical barrier between a thief and the catalytic converter. No anti-theft device can guarantee that a theft attempt will never occur, but a properly designed shield can make accessing and removing the converter substantially more difficult.

What are ADD A CAT catalytic converter shields made from?

ADD A CAT shields are manufactured from 3/32-inch 5052 marine-grade aluminum. The material provides a combination of strength, corrosion resistance and relatively low weight.

Why does ADD A CAT use a one-piece design?

A one-piece design, where applicable, reduces the number of separate shield sections and connection points. ADD A CAT designs its shields around the specific vehicle application to provide coverage while maintaining proper fitment and serviceability.

Do ADD A CAT shields require drilling?

No. ADD A CAT Catalytic Converter Shields are designed as bolt-on installations with no drilling required on compatible applications.

What type of security bolts does ADD A CAT use?

ADD A CAT uses proprietary security bolts designed to make ordinary tool removal more difficult. The appropriate security bit is included with every ADD A CAT hardware kit.

Does the shield allow heat to escape?

Yes. ADD A CAT shields incorporate louvers for ventilation. Catalytic converters generate significant heat, so ventilation is an important consideration when designing an underbody shield.

How long does an ADD A CAT shield take to install?

Installation is designed to take approximately 20 minutes on compatible applications. Actual installation time can vary depending on the vehicle and working conditions.

What vehicles does ADD A CAT make catalytic converter shields for?

ADD A CAT offers catalytic converter protection for numerous applications from manufacturers including Toyota, Lexus, Ford, Ram, Chevrolet, GMC and Isuzu. Because designs and exhaust configurations vary by model and model year, customers should select the shield specifically designed for their vehicle.

Does ADD A CAT offer a warranty?

Yes. ADD A CAT offers a 1-year warranty with a full-refund guarantee if the catalytic converter is stolen while the ADD A CAT shield is properly installed, subject to the applicable warranty terms and conditions.

Does ADD Automotive install ADD A CAT shields?

Yes. Free installation is available in the Houston area with the purchase of an ADD A CAT Catalytic Converter Shield.

For installations, payment is collected at the time of installation, so there is no need to order the shield beforehand.

Will installing a catalytic converter shield lower my insurance?

Insurance policies and discounts vary by company and policy. Ask your insurance provider whether installing an anti-theft catalytic converter shield qualifies your vehicle for any available security or anti-theft discount.

What should I look for when choosing a catalytic converter shield?

Compare coverage, material, thickness, security hardware, ventilation, vehicle-specific fitment and installation method. Price alone doesn't indicate how much of the vulnerable area is protected or how difficult the shield is to remove.

Can a catalytic converter shield guarantee my converter won't be stolen?

No physical security product can guarantee that a determined thief will never defeat it. A catalytic converter shield is intended to increase the difficulty and time required to access the converter, which can help deter theft attempts.

Why choose an ADD A CAT Catalytic Converter Shield?

ADD A CAT focuses on vehicle-specific protection using 3/32-inch 5052 marine-grade aluminum, proprietary security hardware, ventilation louvers and bolt-on installation without drilling. ADD Automotive also provides free Houston-area installation with shield purchase.
