Hi ICF67. As mentioned Ford don't make moulded mud spats to fit the Titanium's sports body kit so you basically have two options.
The link Deo mentions is
my thread, I found a Chinese ebay seller who has produced mud spats moulded for the side skirts. The ebay search phrase you want is "Mondeo mk4 mud flaps side skirts". You'll only be able to use the front ones - it seems the producer didn't size for the rear valance extensions. Still for $30-ish I was very happy just with the fronts. Here's how they look:
Your other option is to get some generic flat 'rally style' flaps which is discussed in
this TalkFord thread. These are a kind you can cut to shape and fix to the inside of the wheel arch. They're the only option I know if you wanted to put some flaps on the back. This user like me just fitted them to the front:
If you do end up doing one or the other I hope you'll show us the results here in the forums
