Another Exhaust Question Mark VIII Base

[FordFan63]

Hi All, first time poster here. Have owned my Mark VIII for about three years, 78k miles, pearl white/tan, and have a quick question on mufflers. I want to replace my stock mufflers with Borla products. Does anyone have the specific part numbers for the easiest swap with stock that fit best? I don't want to modify anything else on the exhaust. Thanks in advance, appreciate the assist.

most muffler guys can make most mufflers work.
center in center out is common.

the stock mufflers are offset offset on the same side and that seems to be pretty rare in the aftermarket.
