991r vs 991.2 GT3 vs GT3 Touring - Much Louder in a GT3 Touring vs 991.2 GT3!?
Here is an interesting comparison video of the 911r vs winged gt3 vs touring.
i was very surprised about his comments on the reduction of sound deadening (about 3 minutes in) vs the winged version. Can anyone confirm if this is true?

I got this the other day from a Porsche employee:
"Your Touring has a conic airbox with a 5.12 ratio bi-sectional apothem chamber. Aside from the factory-installed BMC filters, the channeling from the single intake design collects at the inner membrane tube, creating an airy resonance. The winged GT3 cannot emulate this sonorous Mezger tonality. When air hits the intake pods underneath the large spoiler, it combines with the rear wing’s Venturi bypass (from the low pressure tunnel under the crevice) to result in a more zinging-like noise. Since there are dihedrals within the two ram air apertures on either side of the fans, any pronounced reverb dissipates by the time it reaches the prism-block airbox. If you ever hop in any 991-gen winged GT3, you will likely notice that your car sounds substantially louder due to this effect."

My friend's 2018 Touring seemed louder (with a drone) versus my 2018 GT3. So much so I bought a decibel meter to see if it was just in our minds. After a series of tests, we determined, to our amazement, that the wing and Touring were nearly identical in sound. Only difference was the Touring had a different pitch... a drone that made it seem louder.
Oddly enough, my 2019 Touring sounds the same as my winged GT3. Almost whisper quite, and no drone. Seems that Porsche may have solved the Touring drone with some minor adjustments? My 911R is much louder than either of my GT3s. And no drone.
