Default Sound Symposer -- configurable? (Or where is cabin inlet?)

Can the intake sound symposer be reconfigured via PWIS?

I enjoy the exhaust noise more than the piped-in stuff, and would like to turn sound symposer off (or only have it go on in Sport Plus mode).

Alternatively, if it is not configurable, where is the cabin inlet part, and can it be blocked?

Somewhere under the cover easy to reach there is something that can be unplugged to turn it off. It is a diaphragm that allows inlet noise but not gas smell into the interior.

It opens in "Sport" mode and is obvious but not loud. Far quieter than my old SC (with the sound mat removed, but so is everything else). I seriously doubt that it could overwhelm the PSE sound so long as you did not have helmet and the AC on full force and the window up!

i much prefer exhaust noise as well, the intake noise drowns out the exhaust note and is monotone regardless of rev's but based on throttle position instead... with exhaust it's near impossible to hear the engine and know the rev's without looking down on the dash

It is located inside the plastic rear cover panel, just under the rear window, inside the car. You can simply pull the rear cover out the then remove the soft fiber sound-proof and then you will see it.

It is like a small hole (1'' diameter) connecting to the air intake. If you wanna close it? i guess just seal it with PVC tape.

Cheer!

It is very simple but if you need pic, please let me know.

Pics would be fantastic. Thank you so much.

The symposer intake is not visible in the very handy back seat removal pics of yours is it?

The pic I saw of the device (a rubber tube with a filter in it) was in the engine compartment rather than inside the car. I am not sure there is a simple hole back there!

at 6:17 it shows the sound symposer. I believe I read somewhere that it leads to the roof sills about the doors to convey the induction noises toward front of the cockpit. I doubt it would drown out PSE which is far louder outside than in anyway except for the neat overrun popping. Induction noise on the air cooled cars (along with gear whine on the early ones) was very much the "classic" thing (along with oil spots on the garage floor).
