Is a high flow water outlet worth the $?

[nickyg]

It's almost time to do My coolant flush/ Thermostat change and I was wondering if it's it worth the coin to replace the thermostat housing with with one of those fancy High flow ones.
I don't have a Temperature problem just looking at a chance to upgrade.

Some will probably disagree with me on this, but that is fine. The water pump if working properly will move much more coolant than you might imagine. I think the most restrictive thing in the system is the thermostat. If not for that, the pump moves enough coolant the system could be completely drained in just a few seconds
