Oh, it looks like they will pretty much cancel each other out.
Actually, all those add-ons will probably get you better power up at the higher rpm range.
Numbers? Hard to say. But you'll feel a difference.

that is true, I have felt a difference, I just haven
t had it dynoed yet,. the Cams Provide Low-End along with the headers, and the Intake and TB provide Top-End. (they do cancel each other out)
I guess if I wanted more low end, I could have gotten a TB with a smaller hole, bigger the hole, more top end.

by doing a search on each mod, youll find hp gains. then merely add them up and waa-laa. you have your approxamate hp gains.

that is what I did at first, but others told me, it wouldn't be accurate. I would have to get a Dyno test to see what gains I actually got. you are on the right track AnswerMan.

thats why i said "approxamate". The others are correct about the dyno (before and after mods) being the accurate measurement of hp gain.

I'd say,
Exaust - 5 HP, Maybe 0 torque (noticable)
Cams - 13 HP (peak), Maybe 30 Torque (at peak)
Intake & 70mm TB - 30 HP (maybe, peak), 15 Torque (maybe)
Headers - 15 HP (maybe), 20 Torque (maybe) 10 Torque (maybe)

Thanks. I'd say, that exaust doesn't add too much, and most of my power comes from the Intake & TB combo, and most of the torque comes from my cams and some from the headers. now here is the real clincher.
because I have headers, will getting a straight pipe help flow, and give a little more HP?

I probably have to get a High-flow cat, or just gut my cats.

If you're thinking open pipes, why not look into an electric exhaust cutout? Only illegal when you decide to make it that way.

Message:
With straight pipes you will get more bottom end torque but you may lose some midrange power, you need a little restriction like a high flow cat.
