3 OEM cats for a New Age: in up-pipe; in front downpipe section; and in rear downpipe section (between front downpipe section and centre resonated section):-

As you can see by what dunx has said, the one in the up-pipe is directly before the turbo's exhaust gas inlet -- so if the cat starts to break up...!!!
