I also what to let you know here in Washington State the theft of Catalytic converters is an epidemic. I know 4 people, including my grandpa, who has had them cut with a saws-all out of underneath their cars.
There are 3 kinds of precious metals in the all Catalytic Converters Platinum,Palladium, and rhodium. Rhodium is worth about 6000 dollars an ounce. And you get about 2 grams of these metals total per Cat. A theif generally gets between 100 to 250 per Cat. And it will cost you on average about 500 dollars to replace your cat on your car.
So all of you that think your jacked up truck is cool, like I do, be careful where you park.
