Welcome to the Wonderful World of Ducati Ownership (tm)
Personally, I'd leave the cans as they are if you really want the termi look, for stickers try ebay. You're unlikely to gain any improvement in performance or sound that's worth the added expense of switching from Micron to Termi.

http://217.199.188.40/xmb/viewthread.php?tid=17890 I've a '97 748, and listed a few things in the thread, but it depends what you want, show or go???
Good choice in bike btw.
