H and X pipes
What is the point (or idea) behind connecting the left bank and right bank together on a true dual setup.
I have an LQ4 with true duals and no such crossover pipe or 'connector'.
Do they typically produce a different sound or help match both banks of cylinders for a V8

The "balance" pipe does make the exhaust sound more uniform and helps scavenging slightly. The H pipe has a deeper, raspier sound were the X pipe is smoother with a little higher pitch sound.
