I had posted a few months ago a thread on sidepipe wraps that also had some feedback on header wraps plus photos of a header. There were concerns of deteriation which I can believe due to how much additional heat the headers are forced to retain which results in accelerated deteriation.But it does work. After a full day of driving, shut the engine off, I can put my hand on the wraped sidepipe and leave it there indefinitely. Last, DEI make a titanium wrap that does not require silicon spray (stinks). Their black and white wraps do still require though.
