I did my own one Al and I'm certainly no mechanic. Can change sparks plugs and small tasks like those but that's it.
Wasn't too hard, took half a day from memory. I do remember the end can and the actual pipes being out of line so a rubber mallet was called in to action, needed a friend to hold the pipes for that bit.
You should be fine. The ecu I got fitted though by a Ducati garage.
