Tried various wraps with none to moderate success. The fiberglass wraps will die soonest. They don't hold up to weather, wetness and wind. The rock wool/mineral wool do ok but... They were all meant for an enclosed engine compartment to control heat. I gave up. I have one stock stainless header left and the other was the matt black version. After over 50,000 miles the stainless looks like the black header anyway. They both have marks on them from the wraps that were. Oh well
