Exhaust Systems

If i'm looking at a 'Cat back' system, does this include the CAT or is it from the cat? Bit of a random question sorry :S

It does not include the cat.Includes middle and backbox only.

As above, its from the Cat (not including) Back

So whats the difference with sport and supersport systems then?
