Wrapping a header works for the cheapness of it . But it does void warrantees and a lot of times put on wrong and don’t help . The coating works same temp reduction don’t absorb oil , don’t rot , looks better than a rusty header etc . Personally I run the uncoated cause my car don’t see salt , I’m Cherokee and the cost can go into other things lol , I do have a section of mine wrapped due to my fuel lines being close but even that shit is coming off .
