MOT day today - came around sooner than I expected

Didn't really get chance to sort out all the issues I wanted to but thought I'd chance it.
Anyway, it failed (as expected really) - but wanted to see if there was anything major up with the car as I'm not the best at diagnosing problems... and it turns out there's nothing really wrong with the car other than the fact it has a de-cat pipe! (a few small issues mainly around suspension etc but I'll be sticking the coilovers on anyway and replacing everything around there soon anyway) I'm pretty happy with that. I'll get a cat ordered in and then take it back to the garage for the re-test next week.
The guy even commented on how good shape the car was in otherwise considering its age. Only the bodywork lets the car down, and that's only due to mindless idiots who vandalised the car under ADS1's ownership! (I will get it sorted - it's on the agenda)
Anyhoo - I've order a catalytic converter from eBay which looked to be the right one - had the same part number (HA6007) as one which specifically said 'H22 import' on a website. Will this fit?
