My new C2S sounds deeper than my old C2S and the baffles rattle less so far. Something changed for sure. Also this one seems to have more mid-range than the old car. I wonder what they did??

No, not the cut out at all. Sometimes I can hear the valve but sometimes I can't hear at all at the same speed. And if i release the pedal, i can hear it loud, but I can't hear it when accelerating. It is very strange.
I think it depends on a combination of speed, gear, engine load and its there so that it will pass the drive by noise tests which are very prescriptive.
I suppose it might also have something to do do with back pressure in the system to smooth out the power/torque curves but somehow I doubt it.
