The CatStrap™ is a heat resistant warning strap that runs down the length of your vehicle's exhaust. In most cases, the mere sight of The Catstrap with its bright yellow warning label results in the best possible scenario., They "Just Go Away".
Otherwise, when a thief, armed with a battery operated saw attempts to remove your catalytic converter, the catstrap converts what is normally a 45 second operation into an extremely time consuming operation requiring multiple cutting blades.
