At MOT time

[-Dan-]

When you've completely decatted the MK2's so basically with

4-2-1/4-1 Manifold
Decat Centre Pipe
Backbox

At MOT time can you simply put the MK1 Centre Section and Cat straight on to the aftermarket mani and backbox? Just wondering how it all works, and what people do really.

Yes, a Mk1 CAT and centre section should be all you need. It depends on your backbox, whether your aftermarket box has the OE flange on or not, if not you will have to cut the centre section a bit to slide your box over.
