Most people recommend an RC40 exhaust or Playmini but Maniflow are good too.
You won't need to replace the cat, just order a system suitable for you year
of Mini and stress you need a cat link pipe.

As Taffy says, the RC40 range is excellent. Don't fit anything bigger that
1.75" bore. It is too big and will only reduce power. The tailpipe size is
not a problem, but it is best to keep the main pipe at 1.75". There are a
variety of options in the RC40 range (single or twin silencer, centre or
side exit, various tailpipe designs, etc)

We have found Play Mini and Maniflow can be quite noisy. If you keep your
cat in, a single box shouldn't be too noisy. If you remove the cat, do bear
in mind that you will still need to meet the MOT emission requirements.

y but if he buys my cat link pipe he can put the cat back in for the MOT
