Hi Andy,
i paid £300 for the Manifolds which are normally £350 i also have the large bore 63mm 200 Cells X Flow Cats, i can't say which is best to go for size wise, but when i looked about on the good old tinterweb, it would seem the larger bore ones let the car breathe better so are the ones to get.
The X Flow cats have made the noise better in my opinion, more throaty and also give a little bit of popping on overrun etc. i'm glad i got those ones.
As for the cross over ones that match the standard ones, i've no idea as i've not heard or know anyone that's fitted them.
Here's a link to Top Gears site, let me know if you want anything and i'll let you know who sorted me out, i have been given a good discount from them.
