Although I'm not Mike I can answer the first.
The centre section did have a cat as standard, but now has just a resonator or silencer instead (whichever term you prefer - they are the same) which is more free flowing than the original item.
I don't think you'd have a problem in changing the downpipe but don't take my word for it. You would hpwever defintely fail an MOT emissions test as you would then have not cats at all in your exhaust system.
