   Been discussing reasons why my cat is rattling with a work mate and he reckons it needs replacing, is this so? Thanks.

   Could be the heat shield rattling against the exhaust. Worth checking just in case.

   I've been through a cat converter sounding like a bag of spanners before, sounds like the ceramic filter is shot. I'm afraid that it is a case of get a new one, just don't get a cheap MOT one or you'll need another one next year.

    I have a similar issue but mine doesn't rattle,it vibrates at around 3.5 rpm,could be some loose bolt?
