Update:
I ordered everything on December 12th.
The Magnaflow y-pipe and a few days later the 2nd cat from O'Reilly. Received each within 2 days.
The Toyota gaskets and exhaust hangers from toyotapartsdeal.com. Received them on December 22nd. They sent them via USPS. I'd be pissed, but at least they sent them.
The Borla cat back exhaust system from jegs.com still have not arrived. Still no shipment notification. They say it is being shipped directly from the manufacturer. Someday, I guess. . There was never any notice before ordering that they didn't actually have the part. If I don't hear something soon I'm going to cancel the order and figure out something else.
Just wanted to bitch, I guess. I miss driving it.
