Well.. I don't want to sound all gullable, but according to the original post of this FAQ, "The thought process is that the greater the separation there is between the wastegate gases and exhaust gases, the smoother the overall exhaust flow."

So in some way, one should be more efficient than another downpipe. If the turbulance really is that bad part, then perhaps the divorced flange is better because there must be an important reason why they have a design to separate the two distinct gasses to begin with. So is there anyone that has experiences with both bell mouth and divorced downpipe before?
