Heat Management / Header Wrap (also for your turbo guys)

[Andy]

I've also heard the same junk everyone else has said. Header wrap works really well except for street driven cars because it does hold in too much heat.

Have you researched Swain Coatings. Their exhaust coating is suppose to be a lot better than jet hot. They advertise that with their coating, headers are warm to the touch even after 30 minutes of idling.
