*Any catalytic converters that have material missing and are not full we will grade as 3/4, 1/2 or 1/4 of the full price when they arrive and we will adjust the price for those converters that rattle when you shake them (that is how you can tell for yourself that it may not be counted as Full. Converters that are cut down past the pipes into the converter or have had the heat shields removed may be identified as different as the heat sheilds are the primary identifier and will be identified and paid as the lesser because identifying them outside of doing an assay x-ray that costs more than an individual converter offers.(see "USA Ceramic Material Only Pricing By Assay")
