OK. This may sound stupid. The HKS Turbo catback came with a flat flange gasket that goes in between the cat and flange. I took the stock exhaust off and it does not have a flange gasket but it has that crushed WASHER/GASKET in between the cat. Do I have install both or just install the flat gasket when I install the hks catback?

Pucture? It has been a while. Is it a donut gasket? I thought it was. You won't use both, meaning an old and new together, but make sure you have the right part.
