Even when taking precautions and installing anti-theft catalytic converter shields, the unfortunate can happen. Given enough time and the right tools, thieves can cut through a low quality catalytic converter shield. When attempting to cut through MillerCAT’s Cat Shield™, the amount of noise and time can make thieves reconsider. This is because of the intricate design and superior materials of a MillerCat Cat Shield™. Not even a Milwaukee Super Sawzall and Diablo carbide tip blade can stand up against our 304 stainless steel shield.
