You're fine if it's the full system and not the slip-on.
Dear Rogue, I own a 1299s and I would like to fit the Termignoni Titanium Slip-on (not the full system). A seller in Germany confirms that it is possible, as long as the right Y pipe is utilized, however the seller does not want to tell me what Y pipe he is talking about. After a research, I found out that only two Y pipes are available from Termignoni: D155Y and D155Y2 but neither seems to fit the 1299 according to the description of these two articles.
Can you please help me?
Thank you
PAolo
