Stillen specs?

So, has anyone here tried the Stillen cold-air/high-flow intakes and exhaust and gotten dyno results from it? Now that the car is decently broken-in, I'm starting to put together a roadmap of what I want to do with it. First mods will be suspension and brakes (I've always subscribed to the tuning theory that you overbuild your handling bits initially to have a platform you can build power into), but I'm not seeing a whole mess o' go-fast parts for the SE-R platform just yet. Stillen's got a quality rep as far as parts go, so I'm just wondering if anyone's got hard numbers they'd be willing to share, as I'd be most interested. I looked also at the Stillen header, but they claim that's not legal for on-road use, and I kinda have to keep this baby legal since it's my daily driver, so I'll need to research and see if it's illegal in all states or just the ones that get AR about emissions. I should probably just break down and call Stillen and ask, but I'm lazy and hate making phone calls. :p

Still holding out on any final decisions till the NISMO stuff arrives for comparison,
