u cant tell what those cats are worth untill you get them off and look inside. then you use a stick to see what percent of the comb is leftif the stick goes in more then 6 inches or so they are not full and will be worth much less took a subaru cat in today, (small import) usually worth over $100, it was worth $29 becAUSE OF MISSING HONEY COMB. those look like off a bronco , it has pre cats las ones I had were $35 a piece the larger ones may well be mufflers. you cant buy a cat off the net by picture ya GOTTA HAVE IT IN YOUR HANDS AND YA BETTER KNOW WHAT YR DIONG, a replacement cat, after marked can be worth as little as $15. many muffler shops across the country take off the original cats and replace them with aftermarket ones and pocket the difference. this has become an all to common practice.
