high price at the scrap yard. The catalytic converters that got

catalytic biscuit there is a lot of surface area for the gas to be

neutralized on.

pollution. After the addition of catalytic converters with platinum

and palladium this number dropped to less than 1g of pollution per

mile. After the addition of rhodium it dropped N/E which is non
