"The power result: A dyno-proven 20 horsepower gain at the wheels on the Dual Throttle Body 350Z, 18.5 horsepower gain at the wheels on the G37 Coupe and 17.5 horsepower on the 370Z. This translates to an estimated 20-22 horsepower gain at the flywheel! For G37/G35 Sedan owners, gains are 14 horsepower at the wheels. No other intake for the VQ can match these power gains!"
Never planned on having to buy a bumper just to get 15 WHP. Then how do i get to about 360 WHP with bolt on mods? 
Anyway Stillen exhaust on order next week! Not sure on the HFC ? After the Stillen exhaust is installed will I even be able to take a stock Nismo? 
Thanks,
Alex

I'll post pics once it's on mine.
You will definitely be able to take a stock Nismo. I would recommend sway bars and spring kit for handling.

Numerous people will tell you that the OEM intakes only become restrictive when compared to stock intakes at high RPM's (6800+). I don't recall reading a thread where someone made more than 10whp after getting these intakes. Did you get a baseline dyno before you installed the intakes? You mention you want to get to 360whp, to see how your car is responding to mods you really should have got a baseline dyno. 360whp will probably be impossible with bolt on's the most I've seen is 320whp. There are your factory freaks out there, I personally pulled 296whp with nothing but a set of test pipes on a dynojet.
You can go with the Stillen exhaust but there are a lot of exhaust options out there right now. Feel free to search or ask any of the members we're pretty cool about giving first hand reviews. Btw you might want a tune after installing the intakes, word is they tend to make you run kinda lean.

Seems there's a lot of info floating around in here, and not all of it is accurate, I'd like to correct some things.
On a stock car, seeing whp gainst of 15-20whp is very common, and really good gains with other modifications such as a cat-back exhaust and/or high flow cats is documented all over the place.
For example, a full write up and dyno:
STILLEN Longtube G3 Intakes. Review, Dyno and Impressions.
Our fascia is not necessary to achieve gains such as that, we've never had anyone see the fluctuation that motoiq did on their testing, and never got enough information from them to see why. We do not feel the difference should be nearly that dramatic, and may point to other things, their fans, etc.
Import Tuner just did a test on these components, and saw gains as well. The magazine issue should be out soon, but others have sneaked the results:
Watch for Import Tuner Maazine - 370Z Mods Evaluation, Stillen/Uprev
The car will NOT run lean just with these intakes installed, and a tune is not required. If you do a full setup, including long tube intakes, cat-back exhaust, with the addition of headers AND high flow cats, it will create a lean condition that should be tuned for. Without the combination of headers and high flow cats, the A/F ratios are safe.
I hope this info helps..
