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.
