These gaskets seem to be made of some sort of thin cardboard outer layer with metal gasket material sandwiched within.
These are being used in an N54 application, between the downpipe and midpipe.
The gasket protrudes a little bit beyond the outside of the exhaust pipes, but I do not think this will present any functional issue.
No obvious exhaust leaks immediately after installation. I do fully expect these to be disintegrated in a few years, though.
