I have a carbon fiber pipe guard that I purchased from Mike at Cycle Zone. It has saved my pants leg and protected the pipe, it gets very warm during riding, but will not melt your pants. While you are ordering a pipe guard, I HIGHLY recommend getting a guard, either aluminum or carbon fiber, for the silencer/pipe junction. My Alpinestars have several parts that are melted from contact with the silencer/pipe junction. I also put a second degree burn on my leg when I leaned against my bike and my leg touched the silencer/pipe junction. Mark
