The mounts for the exhaust on the transmission cross member were there for 2005 and 2006. Because of interior noise resonance, Ford put out a TSB to remove them. Sometime in the 2007 timeframe (mid-year?), they stopped using them from the factory. So, the exhaust is suspended solely by the headers/manifolds and the muffler mounts.
Many aftermarket mid-pipes still have the mid-pipe hangers but, of course, unless you have an early model that has not had the TSB performed, there are no mounts in which to stick the hangers. Some folks actually cut the hangers off he exhaust -- that's what I did. Made it easier to remove the mount to change the shift shaft seal and to change the shifter. Since they weren't sticking into any mounts, they served no purpose anyway.
From what I have read, when the mounts were first removed, you had to buy the entire cross member to get them. I doubt that Ford still makes the cross member with the mounts, but you could try -- likely the cross member you have already priced from Ford has no mounts on it. Other than that, you would have to find an 05/06 that has not had the TSB performed, or you will have to fabricate something.
