ABSTRACT:
A compact, high performance exhaust assembly (50) for an internal combustion engine (20) or the like having a balanced chamber (52). Two substantially parallel inlet exhaust pipes (38, 40) are mounted to a first wall (74) of the chamber (52) and are axially aligned with, but independent of, two output exhaust pipes (54, 56) similarly mounted to a opposing second wall (76) of the chamber (52). Exhaust gas is discharged through the inlet pipes (38, 40), preferably in an out-of-phase relationship or alternating from one inlet pipe to the other. The exhaust gas passes a short distance through the chamber (52) and out of aligned outlet pipes (54, 56). The majority of the exhaust gas flows directly through the chamber (52) without significant expansion. The exhaust assembly (50) increases the power output of the engine.
