The Stovebolt Site Forums The Shop Area Engine Shop Smithy's mufflers interesting delima

I recently purchased 2 30" Smithy's mufflers from a Calif supplier. When I opened them up they were a purtty blu color. As I was checking them over I notice that the Smithy logo stamped in the metal casing WAS ON BACKWARDS as was the INLET arrow?? When I put them on they sounded funny. So I turned them around and they sounded better. My question is looking down the end of the pipe that says inlet the perforated openings are facing down the pipe. However the muffler sounds better turned around which would make the little openings inside the pipe point towards the exhaust manafold. Which is the right way anybody know?
