Wrapping your exhaust pipes retains heat in your exhaust system. That creates hotter exhaust gases, this allows those gases to flow out of the exhaust system faster. This creates a scavenging effect, and it helps to pull intake gases through the system quicker. This helps to lower the intake temperatures, creating more power.
All of our exhaust wraps are asbestos free and made from base high quality yarns. They are all water resistant; they do not cause exhaust pipes to rust. You do not have to soak the wrap to install, instead try wetting it with a spray bottle. Fiberglass, basalt, silica, don’t shrink because they get wet like a cheap t-shirt, soaking the wrap doesn’t cause it to shrink onto the pipe. Wetting it causes it to grip a little more during the installation process. If you do soak it or if you drive through severely high water, be sure you run your car long enough so any water that made it through behind the wrap has evaporated before turning your car off.
