Hi there,
Matt is correct, to an extent. The noise, is really caused, for the most part, by the end links. The bars themselves really do not make noise, if installed correctly.
Personally, I like 02 ZO6 bars myself, but this is a personal preference, NOT anything else.
Progression of predictability when at high speeds in the turns, are what I like best about FE4 sway bars.
I hope that this helps, besttoyou, c4c5
