Abstract
An exhaust pipe for two-stroke, internal-combustion engines in which there are multiple exhaust expansion chambers, each within one another, used in combination, the multiple chambers allow for the combustible fuel/air mixture to be delivered in more optimal reflective pressure waves throughout the RPM range of the engine. By changing the number of the chambers, their size and shape, the design of the exhaust pipe can be tuned for torque and power while requiring a minimum of space.
