CorSport Online Store: Exhaust Wrap & Accessories Exhaust Wrap & Accessories The first step in controlling under hood temperatures is to use DEI's exhaust wrap. This product is designed to keep heat in the exhaust and evacuate it out of the engine compartment. Wrapping your headers will reduce under hood temperatures by up to 50% while providing additional horsepower, engine protection and passenger comfort. All exhaust and header wraps are not alike! We start with a hi-temp fiberglass composite material then add a proprietary coating to enhance heat retention and expand durability. We are also the only manufacturer to add 1/4" guidelines to the exhaust wrap to ensure proper installation without the guess work. * Reduce under hood temperatures a realistic 50% * Improves horsepower * Only exhaust wrap with installation guide lines * Added durability and heat retention Shipping is always included in the price you see inside the 48 lower United States.
