Not being an exhaust engineer, I have to think the importance of placement both relative to the headers and to each other would drastically effect the performance of an H pipe and X pipe both used alone but even more so in conjunction with each other.
I mean used too close together could produce a equalization of pressure at a point where the x pipe is relying on higher pressure on one side to scavenge or somethiing (just example with no real merit but just illustrate point)
