New (used) muffler.. which way is up?

You can see some pictures of how the muffler is setup on page 3 of member miles offshore rebuild thread here: http://www.classicseacraft.com/commu...ad.php?t=16894

My boat despite not having a muffler actually has the mounting brackets for a muffler which are plywood brackets with half circle cut outs for the muffler to rest in.
