Says 1992 Explorer on my screen.

Those will work on an 89 BII with a 2.9 or a 4.0.

There is a bit of mis-information about headers and what they do.
They do look better than most stock exhaust manifolds.

They can change where the power band is, low, mid, or high, they don't add horsepower, they change when you get it.
Factory exhaust system is made for mid-range power band.


Changing rear end gearing can do the same as headers, or add to what the headers did.
