ABSTRACT:
An improved header assembly for use in V-8 engines. In engines having eight cylinders, performance can be unexpectedly improved by utilizing an improved header assembly whereby the exhaust gas from each of cylinders 4 and 7 is routed by means of a by-pass tube to a specific area in a second stage collector while the exhaust gas from the remainder of the cylinders is routed to a first stage collector. Such an arrangement of tubes routing exhaust gas into first and second stage collectors creates smooth, non-turbulent exhaust gas flow through the collector resulting in greater engine horsepower and torque.
