Will a 4"x9" dual resonator fit? (Pre 2nd cat location)

Anyone tried this? Searching isn't finding much. I am designing my future exhaust in my head. What I want to do is the following...

MMW Headers

Magnaflow 11385 in the location just after the exhaust manifolds (See below pic) I am leaning this way because this muffler/resonator is also one of their Tru-X perforated core mufflers. Not only would it work to be a resonator, but it would also act very well as an x-pipe in that location.

2.25" dual pipe all the way back.
Remove secondary cats.
Remove stock resonator.

Magnaflow 11378 either in the resonator location (So I would be able to convert to M-tech rear and dual exit later on) or in the stock location.
