whats the diff. btw CC 4-2-1 one piece VS. two piece header?
2 piece is easier to install, you do not have to remove the radiator fan on the drivers side.
2 piece is heavier though, and can be prone to gasket leaks where the two pieces join.
one piece would most likely perform better, but it is possible to get almost identical flow with each
