Anyway if you guys can bear with me, there seems to be some holes in this thread... or maybe it's my brain So I want to recap/ summarize.
It seems you can get similar numbers with the OEM header-manifolds, what ever they are considered and no cat's these headers off a much broader power band right?
On the same token it seems with the headers, if I read all of this correctly, a new intake doesn't add a whole lot of power right? I didn't see anyone say they changed their intakes after they put on the headers, looks like everyone is either still using the OEM intake or they already had an aftermarket. Do you guys still think it would be worth swapping, You would still get better throttle response, etc right? It seems the Stillen G3 causes the car to run a little lean with these headers? Otherwise the Injen intake seems to perform about the same right, and I suspect would help with the air/ fuel ratio? Or given the minimal gains is it not really even worth getting an intake like that, would I be better off with a more OEM/ shorter style (not sure of a specific one right now?) if it did not come at the expense of performance the lower cost would certainly be nice but more importantly they are much easier to install and service right, besides being better protected from water and other road debris? I don't even like the idea of having to pull my bumper off once just to install them, every time to change filters just seems crazy.

Additionally, can somebody (Tony?) send me the install instructions for these headers and I assume there are some for the exhaust as well?
