The side that faces out is polished and smooth. The opposite side is not and has screws showing as well as the bar that goes across so it's partially an aesthetic issue for me. Also I'm not sure that the exhaust pressure was made to hit that side of the flap. Would it leak? Maybe. Maybe not. Summit talked like it should not be turned backwards. But maybe it wouldn't matter. Sure would be easier to do it that way than cutting and welding again. I'll look at the way it's designed when I get home and see if it would matter. In reality, no one will probably know the difference except me if it were turned backward.
