exhaust popping

Hey guys,
just put in fabspeed single out exhaust to an otherwise stock 87 930. the mod made a huge difference in power. when I pulled the cat out it was severely damaged sounds like broken glass in there. The concern I have now is that I have a tremendous amount of crackling and popping only when decelerating and downshifting. I have heard this is normal, but I didn't really notice it with the stock exhaust. It sounds incredible but can't help but wonder if something is wrong with it. Should I be concerned, or just enjoy it? Also what do I need to do with the line that ran from the cat via metal pipe to a rubber hose on the right hand side of the engine, I have it disconnected from the rubber hose, but it is not plugged, anyone know what that line goes to, and what I should do with it?
