Mufflers Revisited

'Nother muffler question. The stock muffler inlet and outlet pipes are different than each other. They are the same diameter with flanges but one pipe is offset. According to the manual, the pipe that is offset on the muffler is the outlet side, the end with the centered pipe is the inlet. My muffler will not fit well at all in the suggested position but fits great turned around using the offset outlet end as the inlet position. Will this make a difference on function? I wouldn't think it would, but want to be sure.........
I should have slept in a Holiday Inn last night.......

I'm not sure about this either, though I need to know for my Kaiser as well. I wouldn't think that it would make too much difference in air flow, but may make a difference in the noise it makes. Anyone have the answer?

The big difference would be that it would be called a "FLERMUFF".

I'm no mathologist but wouldn't an exhaust silencer installed bacwards act as an exhaust amplifier?
I'm just saying.
