OK, I made a mistake. It isn't my first, and I'm afraid it won't be my last.
The position of the pipes might not be as bad as you are thinking, Alfred.
Please see my picture take from a similar perspective.
BUT, that angled bracket I have cannot be correct. If it is horizontal, the tailpipes are not.
Also, I looked at my current muffler, it has the straight bracket like yours, and I can see part of the part number 1301.
So, I will return it (I hope) and get the MB part. I was looking forward to that Ansa sound, but I will be happier if it fits and looks correct.
Thanks for all of your help.
