Ok, so if a head swap is out of the question... and an engine swap and a turbo are just too much money for me now. Are there any other upgrades that I could do to this F22 that can help me out a bit.

If I could get the money, I'd love to swap in an H22. But it would take me forever to save up enough for that. Any suggestions, I've got some suggestions for an AEM Cold Air Intake, I gatta find a deal on that or some other brand. $150+ for one of those, I think, is too expensive. Already have a performance muffler on the way.

How about DC Headers? Would they help performance or just look good?
