Catalyst cell sizes

Not for a Rover V8, but for a Jaguar XKR.
The car was fitted with aftermarket exhaust and freeflow cats, 200cpsi as opposed to normal 400cpsi (cells per square inch).
The substrate has broken down in the cats I have, so I'm buying universal replacement sports cats and welding my inlet/outlet pipes onto them (the exhaust manufacturer wanted £500 plus vat per cat to refill them!!).
I can also get 100cpsi cats, but I've heard differing views as to whether they will be able to pass MOT or not - does anybody have experience of this?
(In my case, it's a 1999 car).
