Thanks MudRunner.
It looks like they made a new section. I'm only worried now because it could burn the dust cover on the new one. (which I split while trying to fit it so will need replacing)
Also I haven't really bent the exhaust more than pull it round at the back. The only thing stopping it springing back is the clamp that goes around the box near the rear which is held with a rubber thing. I have run it to hot and the dust cover shows no sign of burning yet but when I go off road anything could happen.
