Got my PCV wired in the other day, it was the 09-13 kit but wired up no problem in my bike. It's a US version if it makes a difference. Then went to install the auto tune and it seems the o2 bunges on the stock headers weren't welded in but rather a hole drilled and then a thread ring welded on the pipe. I'll get pics up soon. Anyways the auto tune sensors are bigger but threads are the same size. They just barely don't fit through the lip under the threads. I filed it down a little bit and the new sensors fit in perfect so no need to weld new ones. Got some Yoshi's on too I'll post updates when I get her out and see how it works. SAS has been gone and Rottweiler on for almost 3000 miles

Still have the headers off because I was gonna clean them while their off, any tips on how to? Also do I have to replace the exhaust gaskets? And the graphite ring that fits between the rear header and the rest of it is half gone, how important is that? it wasn't leaking before I took it apart.

Replace the exhaust gaskets and the graphite ring while you have it all apart. It's cheap and you'll end up doing it regardless if your graphite ring is already deteriorating.
