Cat Defender™ features

Utilizing Aluminum plating we are able to cover all of your catalytic converter assembly and oxygen sensor while minimizing additional weight.

Our large hexagon vents provide ample cooling of the exhaust system while allowing SMOG technicians to view your EO number to pass emissions testing.

By designing the Cat Defender™ plate  to cover the oxygen sensor, we help eliminate the option for an easy "snip" of the wire.

By using a 2 piece construction on the third generation Prius, we help protect the exhaust pipe in the rear from being cut and making it even more difficult to try to remove the catalytic converter assembly. 

By using aluminum and stainless steel hardware and plating, we prevent any rusting of the Cat Defender™ components.

Our products are not only designed to prevent catalytic converter theft, but they also help improve underbody aerodynamics. This can help your vehicle achieve better fuel mileage.
