I noticed the heat shield started rattling yesterday. As I knew what it was I left it. Its fell off today (stopped and collected) and when I reached home looked underneath. I found the bracket had snapped so removed via the rubber. In hindsight I didn't see any fresh metal so maybe been snapped for a while?

Even at the last mot?

If it is a fail is a new cat expensive and do you get any money off for recycling your old cat?
