Heat tape is a type of thermal insulation that can be used to protect a car by wrapping the exhaust pipes. By insulating the exhaust pipes with heat tape, the tape helps to keep the heat contained within the pipes, which can prevent the heat from damaging other parts of the car. This can be particularly important for vehicles that are driven in extreme temperatures or in harsh weather conditions. Heat tape can also help to improve the overall performance of the car by reducing the amount of heat lost from the exhaust system, which can lead to better fuel efficiency and more consistent engine performance.
