depends what your power goals are. I made over 430 hp with my blouch dom4 and 109 octane fuel @ 27psi with ported and polished sti manifolds. It wasn't until I went rotated that I upgraded to gt spec manifolds.

From what i've read, headers won't make much of a difference until you get into big turbos and all of the supporting mods. Then, there is the cracking issue that seems to plague most headers...
