Headers is a straight pipe. Actually what straight pipe refers to is the exhaust pipe that comes after the manifold whether cast iron or tube headers. What headers do is make a smoothflow for the exhaust. No sharp turns like with a cast iron manifold. Also in racing they are "tuned" meaning a certain diameter tubes at a certain length proven by testing to be optimum for the rpms and flow of the engine for maximum HP. If an engines mainly run at 4000 to 8000 rpm it would require a different size tubing for best scavenging of the exhaust than say an engine running 1000 to 3000 like your daily driver.
