2" stainless chevy couplers

Does anybody make the Chevy manifold flange/donut section in stainless? I'm just using 2" ram's horns and would like this part to be stainless as I'm building the rest of the exhaust system from stainless.

 

You might try a muffler shop that carries stainless exhaust and has a 2 inch chevy flange die and a tube bending machine.......Or try "Stainless Works" a manufacturer of SS exhaust in Ohio...
