Welcome to both of you, this forum has been a HUGE help to me since moving to the 14 last spring.
ZX142009 - Check out my post with pic's here on the KR Tuned slip-on's I have audio samples and pic's etc... I've been riding them for over a month now and are very happy. The fit/finish is excellent, installation fit like a glove, and they sound awesome. I payed $599 for the carbon pipes, but $399 for the stainless is a killer deal in my book.

You can get a pair of them in stainless for $399 on EXTREME closeout direct from HotBodiesRacing.com (which is the sister outfit to KR Tuned products) and I honestly don't see how you could possibly beat that value.

Either way again, welcome to the boards, and congrats on the new bikes.
EDIT - I also wanted to mention that the KR pipes are tuned for stock config and run great with no need for a power commander etc... I'm sure it would only improve things but I have no plans of installing one at this time.
