Actually, it's the opposite. Carbon or not, the upper intake design was available for SRO GT4 racing in the beginning of 2020 (likely in development in 2019) and fitted to the GT4 Clubsport to provide the functional benefit of cooler air into the engine. This was an actual Porsche motorsport part. I have no doubt that one of the things Porsche had to solve when putting the GT3 engine into the Cayman was thermal management for the higher output engine. The upper intake solution that already existed for motorsport was a natural solution for them to turn production-ready. The acoustic/aural side benefits turned out to be a nice bi-product, and something I'm sure they were excited to feature in marketing.
Whether Porsche Motorsport was inspired by Singer's DLS that appeared in 2019, I couldn't say. But there's no question that the development of the upper intakes was function-first, specifically for racing.
Note that the cart below is not an RS, but the GT4 Clubsport Nolasport ran in 2020.
Adding upper intake at qtr windows, yes. But the exposed duct and airbox is imo a "gimmick." Interesting, but nonetheless a gimmick, imo.
On the street, an occasional deep throttle dive to 9K (after making sure no cops around) maybe exhilarating. That sound if sustained driving at >7000 is too much, imo. Becomes painful and exhausting, rather than pleasurable.
Otoh, guess that's true of most truly pleasurable things in life: gotta take 'em in small doses!!

Porsche is allowed to do things which make the car exciting, without adding to performance. It’s a track car which can be driven on the street, not a race car.
They made the 4RS rather extreme because it’s the last ICE Cayman. It’s not a car for everyone, but for those who appreciate the extremeness, it’s a highly desirable car. No need for non-owners to cast aspersions, and no need for owners to be defensive.

I first saw the prototype of the GT4RS May 2018 at Weissach. That thing’s been running for a while also. One of Singer’s investor was with me during that trip. So the DLS intake definitely came after Porsche.
The prototype intake mostly looked like the Clubsport version, but much more crude and rudimentary, It literally was just 2 pieces of plastic tubing from the side window then make a U turn in the trunk to line back up with the throttle body, which was facing the trunk.
The side intake was a road car thing, headed off to Motorsport side for debugging and development then back to the road car. The GT3 engine breaths more air and the side intake is one elegant way to feed more air into the engine. The refined and polished look of the production carbon intake manifold is well, much better looking than those plastic bits during development.
Also, the car was meant to be driven spiritedly, so the intake roar will be a crescendo of sound. It doesn’t stay at one sound or one sound level. For those that deemed the car too loud inside, you are using the car wrong, of course the intake roar is going to be loud if you drive at a constant 7000rpm on the freeway.

Very cool! The SRO approved version was pretty crude in itself as well—regarding the intake routing and airbox. They wouldn’t be too concerned about cosmetics for the race car as long as it worked.
I’d imagine it was pretty exciting to see the proto that early. Was it a 981 GT4 in look overall?
and a good one expressed by many non owners here ...
fixed that for you. FFS the cars only 76db at 70 mph, peak power is 8400, you see 9k for laughs that's all , or to hold a gear on some rare corners on some tracks. No one sits between 8 and 9k revs ffs.
The noise thing on you tube is over done, the car sounds ***** mega. I find my car very quite upto 100 mph part throttle, 85mph on the motorway is no more noisy than a 718 Spyder, it might even be quiter.

So, Singer "borrowed" the DLS intake from the GT4RS?
I am not knocking the 4RS. I do agree it is a special car. It has grown on me. That said, certain things about it are just... off.
In all the (modern) Ferraris I've driven, when you dip the throttle, once the rev happy engine hits ~4500 rpm the exhaust bypass valve opens and at that exact moment the car takes off. You feel that bump in torque (suspect just a matter of throttle mapping) at exactly the same instant you hear the bump in exhaust note. Yes, such non-linear power delivery can be a handful on track, but it is thrilling on the road. In the 4RS, your "crescendo of sound" is not matched by a crescendo of power delivery. Power delivery remains resolutely linear. Without the "crescendo", that's fine. I've driven other high-revving engines with that linear character. But, in the presence of that raw and wild crescendo of sound, the disconnect between sound and power delivery is disconcerting. And disappointing.
I also don't find my 4RS too noisy for long trips. Its a hugely involving and exciting car to drive at all speeds. The 992GT3 is boring in comparison and also way too big for UK B roads. The noise only becomes very loud for a few seconds above 8k revs but how often are you there at legal road speeds !. On track where you spend more time at 8k revs the helmet does a pretty good job muffling it whatever. A real non issue IMO coming from an owner who has done 4k miles and six track days in it and many more planned.

I agree with you somewhat on that one. For whatever reason, the 4RS lacks mid-range punch as compared to even the 992 GT3 and 991.2 3RS. But it's not a big problem, just keep the revs up if you want the car to feel fast.
