De-cat on Standard 197 Exhaust System with Pictures

.it's not really a case of unbolting the cat and putting in a decat pipe mate. The cat is built into the centre section of the clio. You will prob need to go to an exhaust place and get them to do it for you.
Or if your handy wi a grinder and a welder have a look and see what you think, you can maybe do it yourself.
