General Muffler question

My question is about installing a dual inlet and dual outlet mufflers, Flowmaster 50 and 70o series big block in specific. On either side, can you use one of the connections as an inlet and use the other one as an outlet? Basically, I am asking if each side dual inlets (or outlets) have to be both inlet or outlet only? I hope I explained it!
I have on hold for over 30 minutes more than once at Holley's tech phone line!!
