What to get, most hp/tq gain, best fit without scrapping it to death =x......ITR, Kamikaze, JG, i found also a guy that can make a modded JG header with a 2.5" collector at http://www.importbuilders.com, maybe that would be sweet? whats should i get 2.5" collector, 4-1 or 4-2-1? Whats an anti reversion camber? Or just pay someone for head, thats always good.
