This invention is a light weight, high heat resistant composite exhaust, header/tubing system for an internal combustion system constructed out of fiber and resin. The carbon fiber composite exhaust, CMX invention employs fibers and resin, but is not limited to carbon fiber and alumina-silicate resin. To accomplish the objectives of the present invention, the fiber system is first molded into the desired component by using a collapsible apparatus. Secondly, a single layer of fiber material such as, but not limited to, carbon is applied to uniformly cover the component. Third, the resin is evenly coated by brushing, injection, or squeezing method, and is pushed through the uniform weave. Thus, when the resin has been converted to a ceramic by means of the firing process, the mold can be removed to reveal the first layer of the composite. In order to achieve the desired stiffness and rigidity the following steps must be performed a number of times, depending on the application that will use the exhaust component.
