Design Engineering exhaust wrap is used by competitors, car builders and enthusiasts all over the world, and is the first important step in controlling under bonnet temperatures. It is designed to keep heat in the exhaust and evacuate it out of the engine compartment. Wrapping your headers will reduce under bonnet temperatures by up to 50 percent while providing additional horsepower, engine protection and passenger comfort, thanks to improved exhaust scavenging and reduced intake temperatures.Reduces under bonnet temperatures improving engine performanceProtects components and bodywork from extreme heatImproves exhaust efficiencyCapable of withstanding temperatures up to 1200°F (650°C) direct heat, up to 2000°F (1093°C) radiant heat.It is constructed from a high temperature fibreglass composite material with a coating to enhance heat retention and expand durability, whilst being able to withstand direct heat of 650° C.
