I like these mufflers because they are quieter than others.

The best I can do for you is this photo from their site. If you look down to the right where the 50 series big block muffler is. Looking at the internal of the muffler, it's designed to flow one direction through the case. Flowmasters have their internal baffles which are design to deflect air flow for sound. So they have to be used in the direction intended.
