I have both of these on my C14, and they are fantastic. The pipe is LOUD without the optional silencer... but loud pipes save lives, right?
The windscreen is the PERFECT screen for the C14. Put it down, and it's similar to the stock one all the way up, plus better side protection. Put it all the way up, and I can ride with my faceshield open all the way, and no buffeting.
Good luck with the sale, these are the best add-ons IMHO.
