what kind of h.p. increase should i be expecting with CAI, underdrive pulleys, headers, and exhaust. all of this being on a 1997 GT.

what type of headers? long or short? exhaust? midpipe or catback or both? with a full exhaust and longtubes with the cai and pullies i'd say about 25 or so!

With a NPI car you will be lucky to make about 210 WHP.

MM&FF did a huge story on the "project redheaded stepchild". With all the boltons they were just not getting good results.

For probably right around the same amount of money, espcially if you are gonna get LT headers, you can do a junkyard PI swap and make much more power.
