Product highlight – Lava Exhaust Wrap. Sure it doesn’t help us sell more if we mislead you and say the crushed volcanic exhaust wrap takes 1800°F like some other people, but at least we sleep better at night! If you have had problems with another brands header wrap becoming brittle and falling apart, it is because it was too hot (we have a solution for those applications too, Inferno Header Wrap) Magma is liquid at 1800°F, basalt is a mineral found in lava. So really, it any basalt wrap should say 1200°F operating temperature, with a peak temperature (that's for less than 30 seconds people) of up to 2000°F.
