All I run are the PC works pipes, they look so much better than the plated pipes. If you take care of them they don't rust, that means wash your bike and WD-40 it right away, if you leave mud on it can stain it. Naval Jelly works wonders on light rust, no elbow grease, but you have to take it off, and as an added bonus you get that white metal look with the seams darker. As far as plated pipes, if you run in rocks they get little dings, not dents just enough to rupture the plating, then they rust in those spots.
For me it's Works all the way, my .02
