I am looking to customize my project fiero where I will run the exhaust in the center
with a Borla muffler .The muffler I am looking at the Borla xr1 has one inlet and one outlet
I assuming a muffler shop can still run the muffler in the center with a 2.5 inch inlet/outlet
and two exhaust pipes coming thru the center for my 3.4 ?

This sounds similar to what I did, I have a 3800sc, borla boomer and center exit. Mine is on a kit car body though. I haven't started it yet, so I don't know how it sounds.

Here are some pics:
