Exhaust wrap is an automotive product designed to wrap exhaust manifolds and headers to reduce heat. While most exhaust wrap is available in rolls of various sizes, distinguishing which wrap is ideal for your application is important. In the video you will see two types of wraps discussed. Although glass fiber wraps are more affordable, they are stiffer than wraps made from pulverized lava rock. Because a stiffer wrap makes it more difficult to conform to pipe bends, titanium exhaust wrap is preferred by many vehicle enthusiasts. Titanium exhaust wrap, which is made from pulverized lava rock, is also rated to handle heat up to 1800°F.

The website noted above is a good place to visit if you plan on installing exhaust wraps on your vehicle's exhaust manifolds or headers. They have an application chart available so that you can quickly determine how much exhaust wrap you will need for your car or truck.
After applying titanium exhaust wrap on my headers, a simple thermometer determined that my engine compartment heat was reduced by almost 50%. Besides gaining more horsepower because of lower operating temperatures, less heat actually extends the life of other components within the engine compartment. For an inexpensive product, which is relatively easy to install, the thermal benefits of exhaust wrap exceed more expensive automotive aftermarket solutions.
