How a Tuned Pipe Work: When the engine fires it detonates the fuel mixture in the combustion chamber, pushes the piston down, opens the exhaust port and allows the burnt gases to escape along with the sound wave produced when the engine fired. The negative sound waves pull the exhaust gasses out of the exhaust port, and sucking the fresh inlet mixture through the transfer ports, filling the combustion chamber and some fresh inlet mixture go out into the header of the exhaust .
The positive sound waves, reflected back from the convergent (baffle) cone, force the extra fresh fuel mixture (that is now inside the exhaust pipe, and would otherwise been lost) back into the combustion chamber through the exhaust port moments before it is finally closed, (and since after the transfer ports was closed) thus acting effectively as a supercharger turbocharger on your 2 stroke engine.
This happen at very close tolerances individual to each engine specifications and with the correct dimensions can boost Horsepower by up to 40% above standard tune depending at the present state of tune of your engine.
