Akrapovic Retrofit Catalytic Converters VARIOUS VESPA GTS/GTV

"Akrapovic retrofit catalytic converters: When some Akrapovic exhaust systems are installed, the original catalytic converter is discarded. For these systems we offer an Akrapovic retrofit catalytic converter, as otherwise the EC approval would lapse. If necessary, please see ""important notes"", which are attached to the exhaust systems. Akrapovic uses high-performance cats which are guaranteed to give you the enhanced sound and performance boost that you expect from Akrapovic exhaust systems. The catalytic converter is a honeycomb structure made of metal, which contains valuable metals (palladium, rhodium and platinum) on the surface. These metals convert the toxic carbon monoxide and unburned hydrocarbon in the exhaust gases into non-toxic carbon dioxide and water vapour."
