If you decide to try to do this, email Kolak (firstname.lastname@example.org) for a price on the appropriate universal cats.
I wasn't quoted any less than $100 per cat just to cut out the old and weld in the new. The problem is that they are so close to the oil pan, it's difficult to weld around it. $700 sounds about right for that job with their markup on parts.
As for the direct replacement linked in the op, you'll still have to cut behind the y pipe and weld the new one in.
