I decided to have a look under the car to see if I could see were the rattle was coming from. Had a quick look and noticed a bolt missing out of the U bend to Cat clamp, so I jacked that corner of the car up. The clamp was not loose at all but I put a new bolt in anyway. While it was on the jack I started to have a feel around to see if anything was loose, I got hold of the Oxygen sensor and guess what, it was very loose, in fact four full turns loose. With that done I was confident I had found the tin rattle, check the other side I thought, would you believe it, the other Oxygen sensor was very loose as well, about the same in fact. I was eager to get on my way home from my workshop to see what the ride was like now. Solid as a rock no tin rattles anymore. Check yours everyone, it just may be whats causing your rattle.
Just as a side point my car threw two CEL lights, about a month apart, didn't check what they were because I haven't got the tester yet, so I just disconnected the battery to get rid of them because the cat is running fine. Could the Oxygen Sensors being so loose have caused the CEL light ? I would appreciate a comment on this.
