the problem is there is little demand for such an item. hell there is no mass produced 2.5 inch collector header for H22s which gain big power from it. SMSP, is making one for the H22, but are you willing to shell out about $1,200 for it. not many H22 owners will shell that money out, so i doubt accord owners will. besides, the f22 will probably not benefit that much from it to justify the cost.
I agree, unless this header creates 10hp, it won't be really worth it. Show us some dyno charts once you finish up fabricating, and testing it.
