White smoke when idling

That is an indication of burning coolant. Did the engine recently overheat?
Not burning coolant issue. When you did the exhaust did you take out the catalytic converter? If so, that may be the cause. Does the "smoke" go away after the engine is at operating temp? If so, it may be normal condinsation. Keep an eye for black smoke at throttle or while driving ;)
