Suncoast has confirmed they have delivered a new 2010 Carrara S with the new Powerkit. No additional information is available at this time. I am trying to get info on the owner's comments.

We gotto wait and see!
X51 has more torque, not sure how much of it is due to headers though!

My prediction is that any measured change due to the X51 headers will be less than the standard variations in dyno measurements. Plus, any change that minor will make no difference in driving performance. I put the X51s on my last car, and like the look of them (and how often do we look at them?), but don't believe they do anything for actual performance. I don't buy the argument that Porsche held back so they could charge for them as part of an expensive power package that includes many other refinements for an additional 29 hp.
