Exhaust = +- 10lbs
Wheels = not sure, but heard significant
CF fairings
Engine covers i dont see dropping much, but when you add those to a ton of other little things like smog and other things i cant think of, you may lose another 3-4 lbs.
There is a lot you can do if you really want to get into it, although, it seems what makes you lose weight also makes you broke, those are the expensive go fast part usually.
