If you don't have an air pump on your 560, you are lucky as they are a pain. Mine has been removed and the hoses plugged exactly as you show in your picture. The air pump delivers air down stream of the exhaust valves to the cat whilst it is still cold. These converters do not work until they are hot and this air from the pump will shut off once the engine warms up . . . .
