"H" or "X" Pipe advice Please

I was thinking of installing a “H” pipe in my 3” exhaust system where the green tape is located for a few reasons but, #1 is simplicity of the location. I have lots of room here for an “H” pipe and it makes for the rest of the system to be clean and better for maintenance. The tape is between the two TTI adapters and from the adapters’ straight back to a pair of Spintechs. Questions:
Which is better, “H” pipe or a flowing cross over pipe?
Is the location of an “H” pipe or cross over pipe critical?
If so, how is the location calculated?
Would my location be acceptable for street & Friday night drags? (Just out for fun I’m no John Force…yet)
