The intake on the Duratecs is the single most-noticeable mod you can do besides F/I or cams. An exhaust is a good idea, as the Duratecs just want to breathe - do that with the intake and you'll likely pick up in excess of 15 WHP. No joke.
TB is over-rated unless you're running big cams, a SCT reflash and everything else that can be done to it... word on the street is that the Duratec TBs are good to ~200WHP, easy.
Personally, I'll be going with the Cosworth CAI and the MBRP 2.25" cat-back exhaust. Other popular CAI choices are FocusSport (nice, but the foam filter makes me want to double-check that the element is shielded by the lower splashguard for the intake snorkel), Marcy Motorsports (well-loved in the Duratec community, but Walter Marcy is going through some bad financial times, product availability is spotty) and the F2 intake (nice, Cosworth knockoff but the enlarged-over-stock MAF housing area makes me wonder about metering and driveability, not many have them).
Good luck with the new 07! You made a wise move in not waiting for the 08s, as we're not sure the ST will even survive the designers' onslaught. :rolleyes:
