Control heat in headers and exhaust pipes for additional horsepower and reduce unwanted heat in the engine and drivers compartment. Easy to install, and free of asbestos. Keeping exhaust gasses hotter within the system helps in decreasing density and improves the flow of the gases. This improves exhaust scavaging, which in turn, reduces intake temperatures. The overall result is an improvement in overall performance of the exhaust system and thus an improvemnt in engine performance. - Reduces under-hood temperatures a realistic 50% - Improves horsepower - Withstands 2000°F directly and continously - Only wrap with installation guide lines - Added durability and heat retention
