I also read that h-pipes have power lower in the rpms, while x-pipes have their power higher up in the rpms. Is this correct as well?

From what I understand... that's actually the same thing as he said previously... since you usually get torque at lower rpm, and horsepower at higher (HP = Torque * revolutions per minute * conversion factor)
