Headers on an H22.... dyno proven, or waste of money?!
anyone have a before / after dyno of a header install!??!
I was thinking of just welding on a 2.5" collector to my factory piece - unless someone can prove me wrong - because personally I'm under the impression our manifold is just fine.

It is just fine. Maybe not worth the $$$:HP ratio to replace it to begin with. If you choose the correct one however, you will gain HP.
cool. I've got an extra lower portion laying around, I think I'll just mod that and keep my powdercoated headshield on to cover my factory ****
