So if you dont do that what do you think the DME does? Sets a fault for activation and vacuum leak causes lean mixture faults.
the exhaust valve flapper malfunction does not set a cel. if you unplug the flapper at the solenoid you throw a silent code in the dme indicating an open circuit. if you leave it unplugged there is no code as the component is not an emissions component. if you read the post by ct, the exhaust the op installed is catless, which will throw an emissions error code as there are no cats. the flap has nothing to do with emissions.

leaving the vac hose unplugged will NOT set an emissions fault or cause any kind of lean/rich condition...
