If you are going to drop that much dough, then I would absolutely go with the RMF b16 header. We put a regular RMF header for the B18 on my car and it actually lost power, the primaries were just too big. But he also will make a B16 specific header w/ a little smaller primaries that is the shit. Vteckidd can get it for you coated for right at $500. With the difference in the price spend it on something else. I don't know what all else you have done but I would absolutely reccomend the omnipower flat face race valves as a nice addition to the head. The Stem is the same size as the stock valve so you don't have to change valve guides which is very nice. Plus they give a .3 bump in compression and flow extremely well. Right now I have the DC JDM header w/ 2.5 inch collector on my car, I just bought a set of omnipower coilovers and as soon as I can get a few bucks together I'm getting the RMF B16 header myself. The hytech "budget header" (around 700) made less HP than the RMF on the ITR header comparo that vteckidd did. The hytech header w/ the anti reversion chambers will run you over $1,000. For that amount of difference it is not worth 1-3WHP at best.
