Sound is also generated by the volume of air/fuel it's consuming and turning into power. The same car at 200hp sounds different at 400hp. So the fact that the 996 makes more power than a 2.7L will also give it a louder deeper harsher sound.

There are lots of variables, but displacement, head design, and hp are a few of the main ones. There are a few exceptions to the rule from small cars that sound really good like the VW VR6 motor is well known to have a beautiful sounding exhaust.
