and way less than what the makers of those add ons claim the HP increase is as well. only true way to tell is to do a before and after dyno with a tune. yeah i know there have been proven increases with some mods (like the FI exhaust and the stillen G3) and those are the exception.

yeah, never understood why to take off perfectly good factory headers to add headers
i can see it on the older 350z that had the cast ones vs true headers that was a increase when you added them. cost vs gain with the 370z is not worth it IMO
