I was looking for a full exhaust system for the 14, and after a lot of Internet research I found these guys.
The pricing is GREAT and the service was spot on. Ordered the pipe on Wednesday and it was delivered on Friday.

The Yoshimura Titanium can, Stainless tube full set is here: http://www.jazzmotorsports.com/kawasaki-zx14r-0608-trc-stainlesstitanium-full-system-p-143455.html The full set is $776.99, the slip on set can be had for $40.00 less.
I found the website is a little cumbersome, but the pricing makes up for the effort of having to navigate lots of screens. The search is based on manufacturer, not by model and year, and it slows things down a little.
