Fig. Fig. 1: View of the exhaust system showing the catalytic converter-1975 Corvette shown

All 1975 and later models are equipped with a catalytic converter. The converter is located midway in the exhaust system. Stainless steel exhaust pipes are used ahead of the converter. The converter is stainless steel with an aluminized steel cover and a ceramic felt blanket to insulate the converter from the floorpan. The catalyst pellet bed(s) inside the converter consists of noble metals which cause a reaction that converts hydrocarbons and carbon monoxide into water and carbon dioxide.
