Thumbs down on the heat wrap. It actually will do more harm to the headers than without it. My friend has the BBK Chrome LT's, and they don't look real good, and it's been about 2 months since the install. I have the Jet-hot coated ones, and they look brand new, and it's been about a year and a half. Plus they didn't rust, and underhood temps. are reduced. My truck headers are also jet-hot coated.
