What might help you (and others who might be confused about why there can only be one right answer) is to get behind the physics of what is going on, to better explain the results.
You see, and well-built X-pipe scavenges exhaust gases, much like long tube headers. Alternate to popular belief, long tubes shine in the midrange, where the scavenging effect most takes place.
By definition, scavenging actually increases the airspeed of the exhaust gases to a point greater than they could support by themselves. In other words, the 2.5" bassani X on my previous car flows better than 2.5" individual pipes.
Now, an H - pipe DOESN'T SCAVANGE. That is fact. Nor is it designed to do so. An H-pipe is designed to even the pressure from both banks of exhaust, so the pulses are equalized, for SOUND PURPOSES only. This is well known hot rodding theory, from many, many years ago. It is undisputed.
So, that is why an x-pipe is a better design than an H-pipe, especially for midrange tq. I hope this helps explain what is really going on here. If there are any questions or concerns with what I wrote, don't hesitate to respond, right or wrong: I emplore people to respond so we can successfully put this issue aside.
