Cat bolts

[gregor182]

Hi
I had a cat-back exhaust system fitted a week or so ago, I was driving home last night and the system has fallen off at the cat. My question is, what size bolts do I need to fit the system back on the the cat? Is the anything else I need?
Any help would be brilliant

do you mean from the center section to cat joint or maifold to cat?

If its just cat to center section then its just a clamp which looks a little like this () and sort of hold the ball and socket joint together. There about 2 quid from most motor places.
