the gain from those headers was something like 21 hp. I cant wait, I am waiting on an ASP pulley and I talked to Erik about tackling my own headers, but if that falls through I think I am just going to do the stage 2 you cant go wrong. I am defiantly getting that heat exchanger and Johnson pump. Did you guys read about the C32 twin turbo project? I have had an erection for 24 hours now lol
