I bought a set of the Ebay headers used off of here about 6 months ago and the outlet of the y pipe has a 2 bolt flange with studs 5 inches apart. I am not sure what mates to this. The catback on my truck has a flat flange with the same 2 bolts 5 inches apart but I cant find any kind of gasket that goes in between and I don't have a muffler shop anywhere near me. Can anybody with these same headers tell me what mates to this?

I got some of that "make a gasket stuff" and make one myself. really there isnt a gasket that goes there, I created one because my 2 halfs didnt mate well. When you mate the 2 together just crank them down real well. or drive over to Shawnee to a muffler shop.

The factory exhaust has a slight ball shape that fits in there. A Header kit may only have a flat flange.

I used high temp copper rtv on my y-pipe<>cat-back flange. Been there for a year or so and no leaks yet.

This might be the gasket "type" your looking for.
One side slips into the pip on the flat flange, other side is beveled to seal agaist the beveled connection..
