I have audi and volvo cats, you can pic of them+catalog count consist metal inside, but how it counts? that metal was in new cat or in used one? or that metal per 1kg of honeycomb? locally people buy them for $100 audi and $130 volvo, i think to process them and refine metal(i need about 1 year to save enough to do that) and i really want to know what i will get when i refine them. thank you
