Can someone explain to me why the touring is slightly louder car? Has there been an official acknowledgement of this perceived RL chatter?
It's not slightly louder, it's a lot louder. 3-5db louder. An increase of 3dB doubles the sound intensity but, admittedly, a 10dB increase is required before a sound is perceived to be twice as loud. Notwithstanding this, a small increase in decibels represents a large increase in intensity.
To my ears, it is extremely uncomfortable. I get out of the car with a bad headache and ringing ears. To the extent that I am very reluctant to take the car on long motorway drives anymore.
As some others have suggested, its probably due to the different acoustics between the two cars. Due the differences in plan placement, induction vents and engine hood, I suspect the sound takes completely different paths with a lot more being reflected back into the cabin of the Touring. And I am still not convinced there is not less sound insulation in the GT3T.
The photos show just how different the two cars are in terms of fan placement and induction vents. Also, the GT3 has the vent directly under the duck tail which I bet provides an additional escape path for engine noise that the Touring doesn't have.
Like you, I wish I had a verified technical reason for the differences.
I almost bought this Magnus Walker hotrod a few years ago. One of the coolest things about the car were the mis-matched seats. Kind of regret I didn't pull the trigger.

Chris- Sorry to hear you're finding the car so loud it's unpleasant to drive for long distances. Do you have any ideas for how it might be possible to quiet down the cabin a bit?

wow thanks for the clarification. your thought process makes sense. would be interesting to see what Porsche has to say about this in the future.

Call me a bit skeptical w/your "lot louder" characterization. Here's a test for everyone: Listen to 3 files, all at 3 dB. Take the test. I did better using the 6 db target (see at top).

Curious, how does the Touring volume compare to your 964 RS? You would think the older car would be louder, but the Touring sounds pretty loud in all the videos I’ve watched. Definitely a mega sound, and probably a lot better than the air cooled cars.
