So I found a slightly used FI Catback (CF w/ 12" resonators) for $500! And I just received it today.
I love Car-parts.com. If I want used parts....that's my first avenue. Never expected to find this though. Exactly a month ago, I also found a set of Akebonos for $250 shipped. Car had 19k on it. Might be worth a look. For those who don't know....it's a virtual junkyard site.
