Installed on 2007 FXSTC. Removed factory heat shields and took less than a hour to install wrap. Very easy to use, secured with stainless ties, reinstalled factory shields and fired it up. The wrap smoked for about 20 minutes and then I ran the bike on the highway for some extra heat, was 33 deg when installed. Came back to yard let it idle another 20 mins, there was no more smoke just a slight odor. Could feel the difference in the amount of heat coming from the engine and the exhaust had a deeper tone.

Wrap went on easy with the videos online as instructions. When I put them on they rubbed against the wheel wells while jockeying them around to get it lined up and where they rubbed the wrap frayed badly. I also had to loosen the wrap that was up close next to the bolts to the heads because there wasn't enough room to get the bolts in straight. they look really bad now with all the fraying but I am still going to leave them on to see how well they hold up to the heat now that they are damaged. I would not buy them again unless I had a specific place on the header to keep the temp away from something else in the engine bay.
