pipe to pipe temp muffler fix (91 integra gs)

(Integra GS 1991 3 dr)
If the fumes don't kill ya, the noise will. Windows open. It's raining
hard lately ( when it ain't snowin').
I have a clean break from the end of the rear muffler pipe (far end) at
the bracket connection to pipe "B". The new muffler is on order, but we
need a temp fix b4 my daughter goes #1. wacky or 2. toxic, or 3. both.
Is there a pipe to pipe fix? I would have to go into pipe "B" at the
break/ bracket and maybe outside of the pipe from the rear of the
muffler. It will be more than a week b4 the new part can be installed.
