Paul before you do pull the heat shields put a 1/4 inch spacer behind them with longer bolts and some heat deflecting tape/insulation. That might take care of your heat problems. I am not sure what series you have so yoru heat shield might or might not be like mine.
I got to buff mine up with a rouge wheel and get them up fore sale. They are a good pipe sturdy , sound great at normal rpms and has a good bark when you open the throttle. My beast has just out grown them. I suppose they would be louder if you removed the wrap from the baffle but they have a hell of a crack when you getting on her the way they are.
