GM part number 9220232 is for a 2010 Camaro exhaust manifold collector gasket. Its a metal (looks like stainless) gasket with crush ring of what looks like the old stlye (think lead and brillo pad) material... It has the 2.5" inner diameter.

I also bought a FelPro gasket of the same design but for a 3" diameter exhaust. I may make another set of flanges with the 3" hole. I only bought them becasue I thought they were the correct ones but couldn't get the dimensions. Not cheap at $18 each so I'll see if I can make them work for a 3" exhaust....
