I'm getting a flashpaq soon and I figured nows a good time for headers to finish the exhaust. Who makes a good set of headers for the 4.0 SOHC. The headers will be atleast ceramic coated.

JBA

If anybody has put headers on could you let me know if you have noticed any difference.

Thanks

I have the titanium ceramic coated headers from JBA. Of the available finishes JBA offers, this version has the "highest thermal & corrosion resistance level" but you pay for it. I did the same thing as you mention, and ordered my SCT X3 "programmed" for them.


To be honest I didn't notice any real gains (especially not for all that $$$). Even before I put them on...I found most people here said in general, not to expect a huge difference on the 4.0. I would agree with that statement.

 

what i have heard is that headers are not worth the trouble on the 4.0 sohc. Stock exhaust manifolds are pretty good. People who have done it said for the trouble it is to put them on, it is not worth it. they are expensive and would mainly be for looks.

With the 4.0 OHV though you would see more gains

 

get a SCT XCAL3 Superchips is a just a Ford All gas vehicle tune.SCT XCAL3 is a custom tuner

 

I think I'm just gonna go with the Superchips. Just easier for me, buy and plug it in. Thanks for the info.

 

Hmmm, so the headers are a no go huh? With the fact that they are shorties anyways, I can see how swapping them out really doesn't seem like it would make as much of a difference compared to the Y-pipe or full pipes back. With the Y-pipe having the dual CAT setup, there's got to be a good bit of constriction there.

 

Put JBA's on a 4.0 OHV and noticed a little better performance. I do recommend JBA's, Stage 8 header bolts and Percy's aluminum gaskets it makes it a one time job and wont loosen up or blow out gaskets.
