I had a set of those on my last boat. Just fed them through the large port on the front and let them cross cool. Never had any hot spots on them, even after a hard run. As for the dividers mine did have them so I left them in. I think they equalize the exhaust pulse before they hit the riser to help with scavenging. But I could be wrong! LOL (we are all geniuses in our own minds) I also had to make a set of wedges to direct the tips down so I could run the exhaust through the transom. Still have a set of your interested. They are made from high grade stainless.

Built a set of adjustable exhaust tips

I agree that's way to much pressure! That's just what it is at the hose spigot. I figure though running unrestricted through the engine the gaskets shouldn't ever see that pressure. But I have no idea what is coming out of a pump at 4,000 rpm?? From what I can tell it hasn't blown any other gaskets. Like I said the boat had no regulator or pressure relief when I got it?? And no idea how long it had run that way??. So you think the prv is unnecessary? Just run a valve? From what I can tell I'm running about 120' at idle. But the gauge doesn't even move till 100' so it always looks cool. I just installed the ball valve because I hate gate valves they always seem to stick after a while. But I've also never used them in a boat. Just on home plumbing! LOL. As for the riser gaskets. They are stuck like glue!! I figured soak them in WD and use a mallet to separate them?? What you think?
