There are 2 tuned lengths in a 2 stroke expansion chamber not only the port to baffle cone taper. This video explains why that is and how the timing of both compression wave and expansion wave is critical to peak power. Also showing the image of the compression wave formation at the end of an open exhaust pipe. I provide a simpler calculation to that found in the works of Gordon Jennings and Graeme Bell that does not require conversion to Metric or Imperial and is self explanatory.
