Inferno Exhaust Wrap 50mm(2″) x 7.5mt(25ft) Roll. When you want all the benefits from your exhaust wrap, but require a higher temperature for your header or turbo application look no further than our Inferno Wrap. Inferno Wrap is manufactured from texturized amorphous silica filament yarn, this makes it strong and flexible while able to withstand 2000°F (1090°C) continuous heat or 3000°F (1650°C) intermittent heat. You can actually wrap the header with this wrap, run it, heat it up, and literally unwrap the Inferno Wrap when needed. Simply put there is no other exhaust insulating wrap on the market that will take higher temperatures and last longer.
