ABSTRACT:
An automotive vehicle header system is described as incorporating a collector having pipes of inside diameter slightly greater than the outside diameter of the pipes exiting from the engine heads which are coupled to it. This permits a removable insertion of one set of pipes into the other, for ease of installation and later servicing of the engine and vehicle, and allows for a sliding of the collector towards, or away from, the engine as desired, to controllably adjust available torque and/or horsepower. In a preferred embodiment of the invention, the lengths for the collector pipes are individually selected so as to equalize the total lengths of all pipes from the engine cylinders to the output end of the collector.
