Need flange for custom exhaust, Summit not providing...

[94Blue302GT]

I almost always use summit for like everything, BUT, i can't find a ball and socket flange set on summit. Shoot, i can't find ANY time of socket. I need to have a flange because my exhaust has two different setups for track and street. One contains the cat and muff, and the other does not. This is a turbo car, so i'm looking for a 3" set.
Thanks
