High Flow Catalytic Converters and the P0420 engine code One of the more popular modifications that we sell and install here at DDMWorks is a high flow catalytic converter. Although newer cars produced in the last 10 years have had more efficient and better flowing catalytic converters then in the past, aftermarket catalytic converters can typically still outflow them. This better exhaust flow can yield more power from the engine and also on turbo cars, the benefit of faster response from the turbo.
