White smoke could be the heat exchanger on the exhaust leaking coolant into the exhaust.
Yes it does. There is a heat exchanger just aft of the second cat, which harvests heat from the exhaust stream to get the coolant up to operating...
Once you get finished bypassing the heat exchanger, just do another pressure test. You should want to test your work, before buttoning everything...
