Hall has them in stock for like $800. That might have been a closeout? I don't know. These are made to go out the sides near the stock locations not through the a/c condenser hole. They were made for them by Ford Performance Parts in Washington who is a Ford header specialist.
2" primaries and 2-1/2" exhausts.
I have them on my car and have only good things to say about them. I like the side exits.
