Options:
Center exit:
1) Add 90 degree bend after muffler, tucked behind bumper cover and right next to tire well, add custom tip with 90 degrees built in, add one more hanger. Results, more weight, more restriction, notch in diffuser with nothing in it, not matching other side, so need custom diffuser and if you want to tow a custom hitch design.
2) Add a big notch in tire well to fit shorter muffler and use two 45 degree bends, move charcoal canister that has hard formed lines. Less weight, better flow, much more work, still have the diffuser and hitch issues.
Dual exhaust:
1) Add 90 degree bend after muffler with a passenger side exit cut in at the start of the bend, add very sharp 90 degree bend on drivers side. More weight, no gain in performance, still need custom diffuser.

My take on all this?
Much effort and cost with added weight and or restriction and no added performance gain, actual loss of performance in 2 of the 3 scenario's.
Though I love the looks of a center exhaust or dual exhausts, I have duals on my dually, I cannot see doing this and lowering the performance of the car, I would rather take weight out than add more just for looks.
Do as you will of course, just saying what I feel is important to me.
