Sorry for the dumb questions, but I got my hair dyed a whole lot closer to blonde the other day.

Why use studs at all?  Why not use a stainless bolt?  The exhaust studs on my barely three year old 695 are already ghastly.  I can't see that they have to support a massive load, so they don't need to be high tensile steel or anything...

well anyway does anyone have the Ducati Part Number for the studs?

My local dealer has the nuts covered but cannot find a part # for the studs

I figure I will throw them in the spares box for the future...

Suzuki SV650's are like that. There is a bolt with a hex head instead of a stud and nuts. Let me be the first to say, that is a horrible design on their bike, maybe due to the material. They use a mild steel bolt but its still corrodes to the point where the head will snap if you tug on it enough, then your in for some annoying shit. atleast with a nut you can just cut the nut off and the stud might be rusty. As bad as mine is, NYC rained on grime and acid bullcrap, ive removed my exhaust twice without issue, the nut needed replacement but the stud was good. but a nice coat of grease and road grime might of been why it didnt corrode so much.

Studs make assembly a whole lot easier

Studs are a stronger design since the nut is what takes the stretch, not the torque.  More clamping force for less torque.  Necessary on the Duc?  Dunno.  Unless you break the stud, you also don't need to worry about dissimilar metals, another benefit.
