In my opinion i'd go for the 2 1/2inch. setup as opposed to 2 1/4inch. You will definitly feel it will open things up better and if your worried about dran and noise like i was, you can choose to have a setup that will have no droan but a nice note. I think from memory ford put 2 1/4inch's standard though it's not mandrel bent hence at some places it gets smaller.
Best to ask the guy about the different setup of resonators and hotdogs for the XF. Since your car is a sedan you can get away with using just two mufflers in your new exhaust. I elected to have another hotdog just after the cat as mines a wagon and i don't want droan and loud noise.
The other factor to consider is mild steel vs Stainless. Mild steel is cheaper but will inevitably rust quicker within 2-3years.
Stainless can go for 5 years+.
Just some thoughts.
