Default exhaust smoke after lts ory and catback install

after installing my headers ory and catback i am getting exhaust smoke. It shows up about 2-3 minutes after startup and continues and is a white to light gray color. Is this just the oil from the mandrel bending stil burning off or is the computer dumping a bunch of extra fuel in the engine due to my not having the rear o2s tuned out yet, or could I have the front o2 insufficient switching errors from the o2s being to far downstream to heat up properly that i have heard people have had

All new exhaust will smoke for a little while. But if your always burning a blueish/white smoke....your burning oil.
