I encountered the very same problem. I purchased the DP kit from a Ducati dealer in the Bay Area (I live in Los Angeles but they offered me a great price for the DP kit), and he even told me that he could sell the kit to me but would not install it. I then checked with the Ducati dealer closest to my house, but they would not install it either, due to the same reasons that have already been listed. Finally I called the dealer where I purchased the bike and was able to schedule an install with them. I have now had it installed for about 5 weeks and I am so pleased with the new performance....it runs great, no more surging at low speeds, and the sound is incredible (I chose to go without the DB killers), not too loud but a nice serious growl. Call around to some different Duc dealers or even a performance shop could easily install for you. Good luck...
