Wrapping headers and down pipes is an important first step in reducing unwanted and power-robbing under hood heat. Less under hood heat results in a cooler air charge for improved performance and keeping exhaust gases hotter within the exhaust system helps in decreasing exhaust density & increases exhaust flow. Reduce under hood temperatures a realistic 50% Decreases exhaust density & increases exhaust flow Improves horsepower Withstands 1200°F direct/2000°F radiant Added durability and heat retention Only exhaust wrap with installation guide lines
