A header assembly for an internal combustion engine including a pair of header pipes having discharge ends, a collector mounted on the discharge ends and having a housing directing exhaust gas pulses from both of the pipes to an outlet. The collector is formed to produce the flow of exhaust pulses in a manner fluid coupling out-of-phase exhaust gas pulses in each of the pipes to the others by an amount sufficient to increase horsepower of the engine at substantially all normal operating speeds. The header pipes proximate the inlet to the header collector are formed for discharge of gases along a common interface or boundary of substantial transverse length to effect fluid coupling. Additionally, the collector is free of channeling or protrusions to permit unconstrained transverse expansion of the pulses across the adjacent header pipe. A method of increasing engine horsepower by fluid coupling together header pipes also is described.
