I am in the final stages of putting my 5.4 C-head engine into my 2007 Mustang. I have been playing with exhaust manifolds for awhile, but I need to know if the 2007+ Shelby GT500 exhaust manifolds bolt up to the 1999-2001 C heads? It would greatly simplify my h-pipe/o2 sensor/egr situation.
Everyone quickly would dispute it, but they look like if the bolt pattern matches (or is close enough to egg-out), the GT500 ports are just larger ovals and the c-head may have enough material to seal it up.
The GT500 exhaust manifolds aren't easy to come by and I am running out of time before I just make my h-pipe with the 2001 exhaust manifolds (yes, they fit the s197 chassis perfectly).
