Anecdotally, one head w/ regulator at the start of the project vs 2 heads w/ regulators near the end of the project made a noticeable dip in pressure from each side. I thought the whole project was a bust - like, it was struggling to even rinse the soap off; but looked up ways to increase the pressure and found out about the regulators in the heads. Popped em out, and problem completely resolved.
You can still regulate the pressure manually too, using the valves on the t-connector. Ours are usually only open around 75% because they were murdering out hot water tank at full blast, and we’d run out of hot water with nearly every shower.
