If you're talking about the ones that go between the manifold halves, this might work for you.

I've purchased three of them. The first two failed relatively quickly, and the third one was good for the few thousand miles before I parked the car. I don't know if I had a warped flange, or if I had a bad batch for the first two, but it might be worth a try at that price.
What I would prefer is an OEM gasket from someone that had a crush ring at the circumference of each secondary pipe. There are some Subaru gaskets that are rumored to fit, and it might be worth it to you to go to your parts store and order a few to compare. Couldn't be more than $20-30 to get two or three gaskets on hand to compare.

I will toss my vote in for using the Subaru downpipe gasket, used some snipers to cut off the outside edge of the 3 bolt holes in the gasket and it will then line up correctly. I purchased this one off amazon. Its a multi-layer metal gasket style with rings that re-enforce the area were the exhaust gas passes through.
Its $10 on amazon.
