There is a rattle from the cat. from the above vehicle. Does this mean that
the best thing to do would be to get it/them changed. The exhaust centre
said that it will fail the next MOT and will cost £700 to replace?

Thanks

No because it also might not fail and you will remain £700 richer.

It might just be some hardware or the heat shield. I'd wait for a
failure. Or if you prefer, pay for an exhaust gas analysis outside of
the MOT inspection. Then you will have some time to get it taken care
of rather than right away.
