X for performance, better flow....H for sound....and an H will outperform a stock Y. Let me dig up a post I made on it elsewhere.
I posted this on another board, but it applies here as well...have a look:

I looked up some technical details on the H pipe, and how it generates sound, here is what I found in this months article of MMFF:
"......Now the high and low pressure pulses on the left bank get to become friends with those on the other bank. Not only do the sounds mix, but the low pressure pulses on one bank actually help draw out the hih pressure pulses on the other. Quasi-static scavenging, we call it. Makes more torque, smooths things out acoustically. "
And here is what the article said on the X pipe:
".....the X pipe does exactly what the H piep does, but better, different. Instead of just letting pressure pulsations (a small portion of exhaust flow) bly back and forth across the H tube, the X pipe makes sure that all the exhaust gas from each cylinder bank gets very intimate. To things to understand, destructive interference and dynamic scavenging....
....That is why your X pipe sounds different than an H pip. Less modulation, less low frequency contribution, just 4th order starting off low and rising to a shriek at the top of the tach. It's smoother too, since the enrgy associated with the bank to bank pressure fluctuations is used more effectively to scaveng the exhaust gases"
So it proves your theory, and also proves that the X pipe will make more power than an H. On that prochamber, I am asuming that the sqaure portion of it is completely open, unlike an H, there is a ton more room for the gases to combine.....wouldn't this make even a deeper sound than an H, I assume this is your logic here.
