Default Turbo UP/DOWN pipe. DOH !

Hi all, this may well be a daft ? But I have to know, what is the difference between a turbo up pipe and down pipe, are they one in the same ? I've read reference to both ie Up pipe/Down pipe and 1st decats ??? is the cat in either of these pipes - I know theres 2 cats fitted in all, Cheers folks.............

There is a cat in the up pipe (pipe that connect the headers to the turbo) and then 2 cats in the downpipe.

An up pipe goes upto the turbo from the headers and the down pipe is the first section of the exaust from the turbo
