........., they only need to comply with the 75db limit but that is lower than current cars. The 981 GT4 was in the 90s. That's a massive jump. Fixing the muffled sound is presumably easy. See: Povic, Akra. If it's N/A, you can make it scream again provided the particulate filter and all the other stuff doesn't contribute heavily to the muffling. Even then, I'm sure there's ways around it.
As for the launch, the GT4CS will be testing publicly this summer (starting next month non-publicly) and all of the clubsport racers and members with cleaning ladies seem to think the next GT4 is N/A.

If GT4CS is going to be let loose in a month, at least privately, we don't have to wait long for answers.

The thing about noise limits is that I don't believe they apply to whatever happens when you turn PSE on. It will be measured with everything in its default condition. They may need to stop opening the valves automatically at high RPM and loads but other than that I don't think they'll suddenly need to become very quiet.

If that's the case, then we are in luck! If PSE opens everything up, regardless of the regs, we wouldn't have to worry about it. Thanks for clarifying; great relief!

Obviously, Porsche also gets away with the GT3 sound being what it is, though I'm pretty sure that one only has to comply with 80db because they can wave it away with "this version of this car has 4 seats therefore, it is a different class".

Actually, GT3 doesn't have 4 seats! And, shouldn't a 4-seater have even lower limit since it tends to be just sporty (or, a regular family type) as opposed to a sports car?

What I was getting at is they might be able to say, for the GT3, car x has 4 seats and this is based on it so therefore, we are in a different class. As for the 4 seats thing, after seeing what AMG do, I'm not convinced they could get away with calling it "a family saloon". haha.

For reference, the 2016 Carrera S max is 78db

This car is 3.0T for sure. I'm actually wondering if that diffuser is a clever way to mount an inter cooler? Wouldn't a big cutout like that allow air to move from some front intakes perhaps underneath through the middle with the happy side effect of providing extra downforce. dunno.

I fall in to the camp where there's no doubt it's a turbo motor albeit the 6 cylinder.
