How Does an ADD A CAT Shield Help Prevent Catalytic Converter Theft?
Catalytic converter thieves typically look for vehicles that provide fast and easy access underneath. An ADD A CAT shield covers the vulnerable catalytic converter area and adds another substantial layer that a thief must overcome.
No anti-theft product can guarantee that a theft attempt will never occur. However, a properly installed shield can make access more difficult, increase the time and effort required and encourage a thief to move away from the protected vehicle.
What Material Is Used?
ADD A CAT shields are manufactured from 3/32-inch 5052 marine-grade aluminum.
5052 aluminum is commonly valued for its strength, corrosion resistance and ability to perform in demanding environments. Aluminum also helps keep the shield lighter while providing a durable physical barrier underneath the vehicle.
The material will not rust like untreated steel and is well suited for vehicles exposed to rain, road moisture and changing weather conditions.
Will the Shield Trap Heat?
ADD A CAT shields incorporate ventilation louvers designed to promote airflow and help heat escape from the protected area.
Ventilation is an important part of catalytic converter shield design because catalytic converters operate at high temperatures. The louvers provide ventilation without leaving the converter area completely exposed.
Does Installation Require Drilling?
No drilling is required for ADD A CAT shields when installed on the intended vehicle application.
Each shield is designed to attach using existing factory mounting locations. The system bolts onto the vehicle without requiring permanent modifications to the frame or underbody.
Always confirm your vehicle’s year, make, model, engine and drivetrain before ordering.
How Long Does Installation Take?
Installation is designed to take approximately 20 minutes, although the exact time can vary by vehicle and installer experience.
Installation instructions are available through ADDAutomotive.com. Each complete hardware kit includes the required proprietary security hardware and matching security bit.
What Type of Security Hardware Is Included?
ADD A CAT uses proprietary security bolts designed to make ordinary tool removal more difficult.
A matching security bit is included with every complete hardware kit. Store the security bit in a safe location because it may be needed for future vehicle maintenance or shield removal.
Replacement security hardware and bits are also available from ADD Automotive.
Does ADD Automotive Offer Installation?
Yes. ADD Automotive offers free installation in the Houston, Texas area with the purchase of an ADD A CAT shield.
Payment is collected at the time of installation, so Houston-area installation customers do not need to order the shield online before their appointment.

Is Shipping Free?
Yes. ADD Automotive offers free shipping to all 50 United States.

Does an ADD A CAT Shield Include a Warranty?
Eligible ADD A CAT shields include a one-year theft-protection warranty.
If a catalytic converter is stolen while an eligible shield is properly installed, ADD Automotive will refund the shield’s purchase price, subject to the complete warranty terms and conditions.
Review the current warranty requirements before purchasing or installing the shield.
How Long Has ADD A CAT Been Protecting Vehicles?
ADD Automotive has developed and sold ADD A CAT catalytic converter shields since 2021.
For five years, ADD Automotive has not received a report of a catalytic converter being stolen from a vehicle with a properly installed ADD A CAT shield. This represents customer reports received by ADD Automotive and should not be interpreted as a guarantee that a theft attempt cannot occur.
Are ADD A CAT Shields Made for Specific Vehicles?
Yes. ADD A CAT shields are designed around the mounting points, converter locations and underbody layout of specific vehicles.
A vehicle-specific shield generally provides better fitment and coverage than a universal metal plate. The correct application also helps maintain access to necessary service areas and supports a cleaner installation.
