header ???

Ok after researching a little more I found that I will most likely get a 4-2-1 ceramic header from dc sports. (can't do 4-1 because of clearance issues... lots of speed bumps and gnarly dips/potholes) I was wondering though is a 2 piece better than a 1 piece? I know that a 2 piece would be easier to install but, due to the added weight of the mid flange is it worth it, or does it serve any other benefits?

well the 2 piece has another gasket that you have to worry about....besides that i dont think there should be any problems w/ it.
