Isn't it still under warranty?
Borla makes a 304 exhaust for the Bronco Sport (part #140882), which is just an Escape underneath. The Bronco Sport exhaust may or may not fit.
Otherwise, you could just get a universal Borla muffler and clamp it on.
Maybe if you're nice,
@bdcardinal can give you a good deal on the muffler, as he is a Ford parts guy
There is an OE muffler on
eBay for $650, while still not cheap, it's not $900 either.
Get a 90 degree mandrel bend and a universal muffler. Or a Y-pipe thing and 2 small mufflers (this is what Borla does for the Bronco Sport catback, as it has the same muffler design as your Escape)
