All the energy that used to exit the exhaust and manifest itself as noise is now harvested by the turbo. That's why the cars are less noisy.
And I'm pretty sure we won't see any kind of modification to the current technical regulations just to see an increase in noise levels.
Yeah, in addition to turbos to increase airflow to the engines the ERS system also uses turbos to reclaim energy so there is no straight flow from engine to exhaust tip. I don't think the issue is just loudness, I think the engines just sound slower and they are, being limited to 15,000 and 6 cylinder versus 18,000 and 8 cylinder. I see no way to modify the engines to bring back the scream of past cars without wholesale changes to the engine design and that aint gonna happen this year or next.
I'm not a fan of turbos for road racing, they're fine for ovals where the speed to nearly constant with very little shifting. I have no problem increasing the energy recovery system as they have this year but all those turbos in the exhaust pretty much eliminate the classic engine scream.
