Intake/exhause stuff

[McBane]

I'm getting some stuff for my explorer, does anyone have any idea how much more horse power I can get with the following?

Headers, 2.5" exhaust and a high flowing muffler, 66mm throttle body, 70mm mass air sensor/body, and a cold ait intake with a high flow filter?

I'm told 10-15hp gains for the headers, and have no Idea how much more the rest will add, is a total of 30hp possible??, more? I don't know, do you?

Oh well, I guess I could tell you it I ever get it all, which I might...

I wouldn't get the headers unless your stock manifolds are bad. All other mods are a good idea.

Headers on the 4.0 just don't give good gains-for-the-buck and you could actually lose a little low end torque.

I recommend a chip too.
