Generally the X pipe is installed just after the final collection point. (This term doesn't mean the final area that bolts up, but actually means the final location the exhaust gasses collect in the system)

The X pipe/H pipe debate could go on forever. Both are somewhat tune-able by changing installation location. However, it is generally accepted that the X pipe does the same thing the H pipe does, but with better scavenging benefits.
