Will let you know when mine arrive as I have just bought a set (3/2/09) also bought a PC3, DNA stage 2 and K&N Stage 1, now just have snorkel to remove and goodies to fit.
I have a 2006 model XTX on an 07 plate, thoughtI was buying an 07 bike and didn't bother to check
Maybe then have to book some dyno time, but will start with some maps from here first.
