Where do the highest gas pressures occur in an axial flow turbojet engine?

Explanation:
The highest pressure in an axial flow turbojet core is created by the compressor. As air is compressed, its static pressure rises to a peak at the compressor outlet. The burner then heats the gas, but the pressure changes little due to the added heat, and losses in the combustor and the energy extraction by the turbine cause the pressure to fall downstream. The diffuser before the compressor helps recover some pressure at intake but cannot exceed what the compressor outlet achieves. So, the point of maximum gas pressure is right at the compressor outlet.
