True Dual Vs H/X Pipe performance

Cell

Yes, I know some of you will tell me to search. I will tell you that I have. All the google searches I have gone through all went down to the same thing...

All of them would only go into H vs X pipe and how the X has a better top end vs a H having a better lower end.

The problem was that I found nothing on how a true dual would perform against them. Would you get more or less power?

If someone else knows more about this then please explain it because I have been searching for a while now and found nothing about true dual exhaust performance vs h/x pipe.
