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.
Would you say one would not a center bypass because already louder? Tks
Finally picked up my Touring. Starting to think there may be some differences to the application of sound deadening, or something else that's causing the negative experiences.
The sound is AMAZING. I mean, freaking perfect! The sound I hear in my head when I think of Porsche motorsports is the sound this car makes.
It is loud in the best way possible. Not an assault on the ears; more like a gift. Spent some time on the highway and just wanted to keep changing down to vary revs. Zero drone so far on constant throttle. Is there a particular RPM where it's expected?
Perhaps someone has already suggested this and I missed it, but I didn’t see it in Chris3963’s post above: At speed, the Touring’s rear deck rises up, allowing the extra noise. The GT3 w/wing is fixed. All this talk about induction vents, fan placement between the two cars seems to ignore this fact when trying to prove the Touring is louder.
The primary compaint was the extra noise and drone at 140kph. Seems obvious the Touring would be louder, no?
Can't find the exact post right now, but IIRC Chris3963 made a video showing consistent 3db difference at 0mph, ~4krpm. Measured by a phone app between 2 different cars. So not related to tires or spoiler wind noise.
Just watched it, but he messes up and says “sport” button changes suspension. Lol. It does not, you need to hit the shock absorber button. I love how he suggests mismatched seats as I want to do that.
I was wondering about that too. Are the lwbs and sofa driver and passenger seats the same? Or would you only be able to swap left lwb with a left sofa?

I think the seat controls would dictate what seat can go where.
