What is exhaust heat wrap?

Exhaust wrap is designed to wrap around the manifold and exhaust of a car, stopping as much heat as possible radiating from the exhaust into the engine compartment. This is to help lower the temperature of the engine bay which will give lower intake air temperatures, in turn increasing horsepower.

Why do we need exhaust wrap?

Exhaust wrap

The exhaust system of a car carries out the hot exhaust gas from the engine which can reach temperatures of up to 1200 degrees in some extreme applications. The effects of a hot manifold and exhaust system can negatively impact the overall performance of an engine due to intake air temperature. An engine is designed to run at an optimal temperature which will make peak power, usually the cooler the intake temperatures the better an engine will perform and the more power it will make. In some applications the cooling system on a car is not enough to keep the engine at optimal temperatures, resulting in heat soak to engine components which will dramatically reduce the efficiency and power.

As well as the efficiency and power being affected by temperature, having too much heat in an engine bay can cause unnecessary wear and strain on delicate components that are not designed to operate in extreme engine bay temperatures. Items such as bearings, fluid lines and wiring can become damaged with overexposure to heat.

This is where exhaust wrap comes in, it wraps around an exhaust and keeps in most of the heat as to not let it escape into the engine bay.

Should I use exhaust wrap on my car?

Exhaust wrap

This really depends on how much power you are trying to gain and if you are adding forced induction or power modifications to a naturally aspirated engine. Most cars out of the factory will have an adequate cooling system that will be more than enough to keep the engine bay at optimal operating temperatures, however with more power comes more heat. By forcing more air through the engine and making more power the exhaust in turn will become hotter than standard. Turbos and supercharges are also negatively affected by heat soak and again will dramatically reduce the performance and the life span of these components.

However even a car running standard power can see high enough exhaust temperatures to have a negative effect on the engine if they are driven hard for long periods of time, such as track and drift applications.
