Xbow exhaust heat shield removal

Hi everyone. I'm new to the forum as well as recently purchasing a 2013 hammer. Anyone have a tip on removing these heat shields on the xbows? I know they're not the best pipes, but getting new ones isnt an option at the moment. Do i need to remove the entire exhaust, or is there a way to pull them without? Removing the entire exhaust seems to be quite the pain in the ass. Thanks
