Headers don't add power, stock ford exhaust is tuned for best power at about 3,200-3,700rpm.
After market exhaust can lower that RPM ranger to about 2,500-3,000rpm, you of course lose the 3,200-3,700 power.
Reason people change headers is to get more low end power, giving up mid-range power.

All fuel injected Ford Rangers came stock with CAI(cold air intake) and 200% air flow, so outside of keeping air filter clean there is not much you can do to improve that.
Some like the sound of after market air cleaners, sucking air noise, which is fine, but it can actually take away some power, if you are pulling warm air in from engine bay instead of stock system that pulls in cooler air from behind grill.

Larger diameter tail pipes and muffler can give a lower tone to exhaust, just like a pipe organ uses large diameter tubes to make the low notes.

The 3.0l Vulcan engine is a good reliable motor, but not a power house, really no way to increase the power on a budget, Ford engineers have done all the "cheap" upgrades, lol.
And many drivers are not used to higher RPM engines like the Vulcan, you need to keep RPMs up in this engine, above 3,000, and more like 3,500rpm to get any power, thats just the way it was designed, it ain't a diesel, lol, that has power at 1,000rpm, or a 4.0l that gets power at 2,200rpm.
Maximum torque is 180ft/lb @ 3950 RPM
Max horse power is 148hp @ 4900 RPM
So keep those RPMs up

Super charging or turbo charging is about all you can do to get reasonable increase in power.

One thing you can do that gives better MPG AND more power, getting both is a real win-win, since it is next to impossible to do.
Switch from a mechanical radiator cooling fan to an electric fan.
Mechanical fan draws horsepower all the time
Electric fan does use alternator power but not all the time, usually only at slower speeds when air flow thru rad is less, when driving fast air flow is high and fan is off.

Do some research on throttle body spacers. Some people love them and others say they don't do anything
