That's an excellent point. In addition to the exhaust itself, the timing of the pulses and volume of exhaust flow relative to engine speed play a role. Therefore exhaust closing point and overlap need to be considered.
It'd be interesting to hear people's experience with trying different camshaft layouts and whether they noticed a difference in drone without any change to the exhaust system.
