DEI glass-fiber exhaust wrap insulates headers and downpipes to cut power-robbing underhood heat, lowering intake air temperatures while keeping exhaust gases hot to reduce density and improve flow. It withstands 1200°F direct and 2000°F radiant heat and is the only exhaust wrap printed with installation guide lines for clean, even wrapping. DEI recommends sealing glass-fiber wrap with HT Silicone Coating to extend its lifespan. Do not wrap catalytic converters or flex-joints, and note that wrap stiffens once heat-cycled and is not meant to be removed.
