Again, why bother? I've had both. I installed them on my 07, they worked fine. The tuner I went to laughed and said it was a complete waste of time. A real header will get you some gains, but nowhere near what everybody would like to believe, it just isn't the primary weak link in the system. Do a turbo upgrade first. Anything bigger than a VF, do the injectors. At 350 whp or more then a good ELH header MIGHT net you 10 whp or so, it ends up being a significant mod with not much payback. Main benefits I've got from going ELH are less boomy exhaust, and more even and slightly lower EGT.
Have you done a VF turbo with supporting mods yet? Way better results for similar money.
