They reported the stillen G3 as only 6-7 whp, because it was installed last, and the exhaust system at 27 whp because it was installed first (and 10 whp from the tune). Stillen's site claims 18 whp from the G3 CAI, that is against a bone stock Z. I have seen dyno's of an otherwise stock Z with JUST a test pipe gaining 15-20 whp.

It's a matter of preference, but to say that the gains from the Stillen or any CAI are noticeably different from the drop-ins and HPS hoses is not correct.
