I've wrapped multiple downpipes, headers, dump tubes, etc and this is the hands-down worst wrap I've ever used. As soon as you start handling it, it begins to fray and unravel making it almost impossible to handle. if you need to fit it in a tight space between collector tubes, good luck, it'll fray even more, and when you try to secure the wrap, it just looks like trash. I wrapped one runner and stopped using it. I'll just toss it in the garbage.See full review
