thats sounds pretty chill, but wouldn't getting larger piping like 3" allow for better air flow, after this exhaust gets put on a CAI is going on Steeda looks like the best bet I've been calling K&N though cuz ive used their products forever and they work great for all my other toys, but the big thing I want to do to the fusion is to put this new super/turbocharger combination I read in a magazine think it was called a centrifugal turbo something like that it pretty much was the super charger pully system attached to a turbo. This is just a fun project car.

thats the whole point of the system because this fusion is going to get a FI system
but until that time you are going to kill your low end to hell going with anything over 2.5
Yea, I'd say 2.5 is a pretty safe number. If you NEEDED bigger then I think your pulling too much power for fusion 6 speed auto. Just in my opinion.
P.S. Just bought a 07 v6 mustang MTX and it has a 2.5" on the 4.0l v6.
