Alright folks, I've had these on my car for a few weeks and a few thousand miles now, and its time to report.
First, if you don't already know, PnPnC - Ported and Polished and Coated
Link to product:

Install is very straight forward....take your headers off, and put theirs on.(ha!) A few hints:
1) Start by removing the O2 sensor that's inside the right tire, just below the uppipe, but on the topside of the header. If you can't get that off, don't start. It helps to have an O2 sensor socket.
2) You'll want to put your heatshielding back on, and there are a lot of bolts/clamps, so be careful when removing, and mark locations/bolts if you have to for when you put it all back together. Once you have the sensor off, start from the drivers side and work toward the uppipe.
3) you can do it all with basic hand tools (except point #1) and you'll also want a 10in. socket extension.
Results:
I could definitely tell the difference in throttle response and all the way up to 3500 RPMS via my butt dyno. After 3500 its a little harder to tell just by 'feel', but I'm sure it looks good on a real dyno.
My turbo comes on earlier as well, for my engine, probably about 400rpms quicker. Specifically, in a 2nd gear pull, you could really feel the turbo kick in around 3500 rpms, now I feel the same kick about 3100rpm.
And the best part, 100% bolt-on, NO protune necessary!
Let me know if you have any questions...
OH, and customer service/ordering from GrimmSpeed is really good too, great vendor to deal with.
