Well the wrap's already on. The pipes were scratched up and blued and I wanted to black them out so I wrapped them. Just the headers. I did no other mods. The bike acts exactly as it did pre wrap except the idle fluctuates by about 250 rpms. This is the first I've ever heard of header wrap destroying pipes. I have the same header wrap on my 79 Ironhead and it's been on there for 10+ years with no issues. The idle will drop by about 250 rpms then cycle back up, but only when the bike is hot.
