Review on 🏎️ Superfast Racing 2-inch x 50 Feet Exhaust Heat Wrap Tape with Stainless Ties - Black Fiberglass Motorcycle Manifold Header Pipe Heat Protection Wrap (Color Fade Possible) by Tyler Parker

I used this to wrap my headers on my 302 SBF to keep underhood temps down and to help with a vapor barrier issue. Using the method of laying each wrap in half allowed me to use a 50 foot roll per side. The header pipe temperature dropped from 530F+ to about 420F a few inches from the head. Although I've seen other people say they need to wear gloves after soaking the packaging, I haven't had any issues with gradients. However, I got very itchy from handling it. So if you're having trouble with fiberglass insulation or the like, don't get too carried away.
