shorty headers are worthless and unlike a 5.0 fox mustang they are NOT at all fun to put on. Also, overlooked often but if you wanna decrease temps (slightly) remove the sound deadening hood liner...traps lots of heat
one of mods coming soon...prob next year is venting the side fenders...that should release some heat...

Hey hunter autozone carries low temp thermostats in their lil performance section. Im gonna do electric fans an oil cooler larger tranny cooler both with small fans on temp switches and edge programmer to up shift pressure which will lower trans temp due to less slipage ....sorry if cant spell just had surgery still in hospital full of tubes and hydroMORPHine.
and yet...hes on EF...lol!!!
X10000000000000 about the rusting. And on top of that, I had them on my G37 to reduce the rasp. It worked but the problem is that when it rained or in the morning with the dew it smelled like something was buring since the wrap was getting hot.
I'm probably nuts but I think I found some long tube headers. I did a quick google search and found these: http://www.pacesetterexhaust.com/headers_truck.php#notes
They say they fit 1999 Ford Expedition 5.4L XLT and other years. Is this true? Or are these guys selling bogus stuff? They also have them on Ebay for like $295.00 Someone set me straight.
Get out of the hospital - they have horrible food!! Stay Healthy and thanks for the info. I'll check into it.

I would agree on a bone stock expy. They do not work to scavange exhaust like tuned (long tube) headers. But done as part of a system, say the rest of the exhaust is addressed also, they will reduce back pressure due to the larger size of the primaries. Just like any other mod short of maybe programmer or gears the whole system needs to be addressed. The factory has well matched all the components as a whole so no one component typically by itself does much.
I needed much higher flowing exhaust with my set up. So I went with 1 5/8" shorties since long tubes were unavailable. The ceramic coating was an extra that I went for (seen it used on mustangs) and was amazed at how well it actually works. You do not get the radiant heat you typically get with headers or cast manifold. This is why under hood temps are dramatically reduced.
