2.75" downpipe to 3" test pipe - which gasket to use?

I've been using the 2.75" (70mm) gasket but stopped to think for a second and couldn't come to a determination on what gasket would
be ideal for a 2.75" to 3" flange connection - the 2.75" one or the 3" one?

3"

The extra gasket inside is not really doing anything.
