I have never used thermal wrap but have been working on cars for 20 years. I can say this is a quality product. It was used to wrap the different length manifold along with the top and bottom pipes on the Subaru sti and there is noticeably less heat in the engine bay with limited usage. I can't verify how long it will last, but from what I see and what I've done about Header Wrap, it's exactly what the doctor ordered.
