Cooling systems should only have 14-18psi maximum. Anymore from cylinder pressure leakage into the coolant passage and pop.
Popping the block freeze plugs are much more fun and exciting to see though!

You should replace your headgasket also. If it has enough force to blow out a stock waterjacket plug then 95% of the time your head lifted and you will continue to leak over time until you fix it.
You probably need to take off the exhaust manifold at minimum to access the plug.
You had said water pump freeze plug in your OP. Its not a water pump freeze plug if it is not in the water pump.

Usually caused by a blown or leaking headgasket. It seems more common on 2005 for some reason.

Strange that you mention it seems to happen more on 2005 evos. I wonder why that could be the case? Its not like the water pumps between the years are any different...In my case I popped the filler plug in my water pump. Got that replaced and all seemed fine until two weeks later where I blew my headgasket. I believe that the two instances were related however I am far from an expert.
The HG popped the freeze plug, you replaced it but the underlying cause was still there.
Car's will run fine on leaking headgaskets most of the time.
Our stock engine 605whp Evo headgasket was leaking for 2-3 months. We ran it up to 42psi. It would eat coolant consistently. Still made big power, just needed a gallon of coolant in the trunk. Finally it popped the weep hole in the water pump and we decided to replace both at once.
The water pumps are different on different years. 06 is different and I think there has been a superseding part number on 03-05 along the way.

They are related. They are the same thing.

Resurrecting
Sorry for the Resurrection, but i hate starting threads on topics that have already been discussed a bunch. Anyways...
My water pump plug blew out tonight, and it just so happens that i had just added some coolant a few hours prior to it happening. I added Coolant to the overflow tank, as well as the Radiator. I then drove about 5 miles, parked for a few hours, then on my way home i heard what i thought was a backfire(going maybe 40-45mph @10-20psi maybe) and when i pulled into 7-11 parking lot i saw a bunch of smoke, so i popped the hood and saw coolant everywhere. Then noticed the water pump was pouring out coolant.
Could this be from having air trapped in the system?
