Mates car has a broken Cat matrix.
On my 406 2.1TD a couple of years ago, same happened to me (After 180,000m)
The garage just rodded out the old cat, leaving an empty chamber. No real problems but was slightly more bassy noise. At the time (late 2003), Cat not required for MOT as test was on emmissions.
1. Is that still the case about MOT?
2. Would rodding the 306 be the same as the 406?
Cost would be about £10 instead of £200ish

spend £10 not tested on mot and possible performance gain too
