Akrapovic uses performance-oriented catalytic converters that guarantee the sound and performance increase you have come to expect from Akrapovic exhaust systems. The catalyst is a metal honeycomb structure with precious metals (palladium, rhodium and platinum) on the surface. These metals convert the poisonous carbon monoxide and unburnt hydrocarbon in the exhaust gases into non-toxic carbon dioxide and water vapour. | Article: Akrapovic Catalytic Converter, silver | Article: Akrapovic Catalytic Converter, silver, silver
