Exhaust Flanges - Where?

I need a 2.5" exhaust flange, that I can weld onto my mid pipe. Advanced and AutoZone dont have the right sizes and styles Im looking for. Does anyone local have any? I havent tried NAPA yet, and prefer to stay away from them if possible.

Reason I need a new flange, is b/c my old/current one is rusting, and its bending on me, not pulling the exhaust up for a tight seal. Looking for one along these lines:

Try Napa, but if not, check out KTeller. Guaranteed to have what you need.
