X pipe H pipe or side by side

I remember talking to Doug Thorley hisself about this years ago. He said that although they do offer crossovers of different styles, that they did not make much of a real difference on the dyno. All I remember him saying they did was make the sound different.

I do know that without the crossover.......of any kind, that the exhaust note is more crisp and edgy. I kinda like it like that.

I guess it's like any other mod though. The best place to really find out about any power advantage is on the drag strip.
