Cat Shield Comparisons: The ADD A CAT Difference
Not all shields provide the same level of protection. Before choosing a shield, compare its coverage, material, construction, security hardware, installation requirements, warranty, and overall value.
Why Choose an ADD A CAT Shield?
ADD A CAT shields are engineered to create a strong barrier between thieves and your vehicle’s catalytic converters. Each model-specific shield is designed for proper fitment and practical protection without unnecessary modifications to your vehicle.
Marine-Grade Aluminum
Our shields are manufactured from durable 3/32-inch 5052 marine-grade aluminum. Aluminum provides strength and corrosion resistance without adding excessive weight beneath the vehicle.
One-Piece Protection
Many ADD A CAT shields feature a one-piece design that helps reduce exposed areas and potential access points. When comparing brands, look closely at how much of the catalytic converter area is actually covered—not simply whether a shield is present.
Proprietary Security Hardware
Every ADD A CAT hardware kit includes proprietary security bolts and the matching security bit. A shield is only as effective as the hardware holding it in place, which is why security hardware should be an important part of any comparison.
Bolt-On Installation
ADD A CAT shields completely bolt on with no drilling required. Most installations take approximately 20 minutes. Houston-area customers can also receive free installation with the purchase of a shield. Payment for local installations is collected at the time of installation, so there is no need to order the shield online first.
Ventilation and Warranty
Built-in louvers provide optimum ventilation around the exhaust system. Every ADD A CAT shield is also backed by a one-year warranty with a full-refund guarantee if the catalytic converter is stolen while the shield is properly installed, subject to warranty terms.
ADD A CAT has delivered five years of proven protection, with no reported catalytic converter theft from a vehicle while our shield was installed.
