I wrapped the header pipes from the top to the end of the cat on the wife's 2010 TriGlide. the heat sheilds fit back on perfectly and there was a great reduction in heat!

I would never use the stuff personally, wrap holds in too much heat and holds moisture and will crystalize and the pipes will crack. Was gonna wrap a set for a SB Chevy one time and Hooker said they wouldn't last long, and two years ago my buddy wrapped just his rear pipe and it snapped goin down the road... ceramic is the best and only way to go IMO....
