Anyhow on Sunday, I clambered underneath as the exhaust was knocking somwehere terrible and found it broken!
The pipe that comes over the rear sub has broken going into the front of the backbox. They are still connected as the pipe flange is inside the backbox section still, but it was pivoting and moving and allowing the whole thing to sag until the exhaust pipe was resting on the sub. So I have gotten some metal coat hanger wire and used the two holes in the sub to suspend the whole thing and it seems to work ok.
Anyhow I then went through the paperwork I got with the van with a niggle in the back of my head, I found what I was looking for. The excuse for an exhaust was put on by Kwik-Fit in July this year, and I had found the receipt.

It was fitted in Devon, but the warranty should still hold for any branch of Kwik-Fit? What do you guys think, can I get it replaced?
And I am thinking that when it is replaced that I will put the coat hanger wire back to stop it dropping and breaking like that again.
Ta Much.
