glasspack help!

here is what i have. LongTube headers into true dual exhaust that dumps before the axle. Today at work i swapped out the old mufflers for thrush glasspacks. I was not even thinking till i just got home. stupid question but can i install them backwards by mistake or can i damage something if one is the right way and one is backwards?

The style of glasspack I'm familiar with was directional. I know alot of people that intentionally installed them backwards to make their vehicles louder.

It should not matter with the thrush. From the picture I found on Jegs website they are a straight through inner pipe with holes and the packing material around it. The ones I was thinking of had an angled louver to direct the exhaust into the packing material and they were labeled inlet and outlet as well.
