where is the flex section on the down pipe? cause if its under the car, it should be smoking under your car, if its in the down section, then if your smoking then you might have a problem in your engine, what color smoke are you getting?
Could be however it's much more likely that you have a leak between your elbow and the downpipe if the smoke stays in the engine bay.
(I've had this problem)
