I don't have any experience with modular engine headers personally, but i had to take my PS exhaust manifold off to replace 2 broken exhaust studs. I had my buddy who's a mechanical engineer sand blast it for me and he said "look how they make these things now, I saw a show on how they use fluid dynamics to engineer them for best flow". Its up to you but considering how much of a pain it was to take 1 side off mine, the money, and the fact that you probably won't find any felt performance gain on a stock motor, you may just want to stick with the factory set up. Just my $.02

hey, i wanna put a set of headers on a 4.6 Expy. ive seen some from pacesetter, Gibson and BBK performance.
Pacesetter mild steel: ~$200
Gibson stainless: ~$470
BBK Mild steel ceramic coat: ~$470
anyone else offer anything? also, are the Mustang 4.6 headers usable? im unsure if the exhaust flanges are the same for the mustang version 4.6 and the expy version 4.6.
if anyone can confirm that the truck 4.6 is the same as the Mustang GT 4.6, then its entirely possible that the mustang headers could be used on the Expy, provided there is enough room in the engine bay.
