I find it difficult to believe you cannot get an off the shelf replacement for a 2006 vehicle!
Is it a Ducato base, if so search the adverts for one that matches the base vehicle rather than the motorhome type.
The only likely difference will be if the converter changed or replaced the tailpipe section, if so that can be easily overcome.
Or at least let us know which base vehicle and then possibly you'll get some recommendations.
