Not sure but I believe some mufflers are directional, but how you tell with these I don't know. Check with your supplier. For me if they were straight through, direction makes no difference, because it the holes in the through pipe and the surrounding baffling that does the work and that should work in either direction. But if you can't see through from end to end then there is probably a right and wrong way. Threads could be for the extension or the mount to the engine.
I'd put them back on the way you have them now, they are working, so install them the same way.
