So...
Dual Exhaust: +5 or 6
JBA Headers: +7-ish? (honestly, no idea. Maybe as high as +11hp out of these but I think that's a little much)
CAI: + ? Not sure. CAI+tune = 12-ish hp, what does a CAI by itself do? Anything? +3 hp without a tune?

I'm not exactly sure (and I'm probably WAY off) but if I had to guess I would say something in the neighborhood of 225?? Depends on what CAI you have and if you have Tuned your Car too. If you haven't tuned it then do yourself a favor and go buy a tuner!

ok 5spd or auto? if it is auto i can give a slight idea from all the research i have been doing
With the mods you have now if your an auto you are probably putting aroudn 185-195 at the wheels with the 195 being lucky.
i just had an 08 dyno tested with the dual hpipe and roush cai, it put down 183.3 at the wheels. with the custom tune and 91 octane we hit 198.8
so i would say if your an auto with your headers vs my no header upgrade you would be very close to 190 max. get it dyno tested and a tuner and you'll be right at the 200 mark, maybe even 205.
now i am not sure of what they 5spd would give you on those numbers. you'll hvae to get that answered by these guys. but i just had all this done 3 days ago

With the exhaust.. you really don't gain HP because you didn't change the cats, plus are you running an H or X pipe? Some people feel a loss of power with the H, some feel gain with the X. I would think you would probably get like 3 rwhp with the x-pipe, its more sound than anything.
Headers are kinda the same deal, maybe 2-3 RWHP.
Now for the cai, do you have a tune or just a cai? If you just have a cai thats probably just another 2-3, but if you got a good tune probably around 12ish rwhp.
Also you have a auto or manual? Manuals are 180 rwhp stock and 165 for auto, so I am told.
conclusion
MANUAL: high 190's with tune. high 180's without tune
AUTO: mid-high 180s with tune, high 170's without tune.
I am not sure about the RWHP stock for the auto and manual, that is just speculation from the info i gathered from these forums.

Internet benchracing is BAD BAD BAD! There are so many variables. The OP referenced crank HP, but a dyno measures rear wheel horsepower (rwhp). HOWEVER different dynos give different readings. A DynoJet will give higher results than a Mustang Dyno. Atmospheric conditions will affect the results, even if you run the same car on the same dyno with the same mods on different days.
That being said, the stock single V6 muffler is restrictive, and replacing it with a GT take-off has shown gains of 8 rwhp. Duals with shorties (IMO) probably will give you 10-12 rwhp OVER STOCK.
Your next upgrade should be a handheld tuner matched to a CAI that requires a tune.
