"Dry" exhaust and Cam Selection Question

Registered
There are two different levels of dry exhaust. Both are ridiculously loud.
Fully dry is jacketed tails that are closed at the tips and have a water dump welded in that dumps the water overboard through a thru hull fitting. You will have no chance of reversion this way.
Dry to the tips is a jacketed tail that is open at the tip so water mixes behind the transom. Very little chance of reversion. My tails are dry to the tips and I still get water back to the collectors at idle, none in the oil. My cam is a good bit bigger than that one though.
Just to point that out.

That is what I was told by someone else as well. Thanks for the other info too on the alternatives.
