Just a quick question, then...
I looked up the OEM stock silencer price in the Ducati parts catalog and the stock replacement cost is $2,600. What does one do if and when they want to sell? I have heard them cored and they sound great, so if you are doing it just for the sound, then it makes perfect sense. However, some folks are trying to save money by avoiding the cost of $2,000 slipons, instead having them cored at < $400. Unless you find a pair that someone is willing to sell you, it will cost you big time in the long run if you want to take it back to stock, lower your trade in value, or delay a sale.
This being said with all due respect to a highly regarded member of this forum, of course.
