Sound Symposer - where is it on a cabrio?

Hi,
I recently bought a 2015 cabrio. Does anyone have info about how to defeat the 'sound symposer' noise? Where is the 'pipe' in the cabin?
Also...is there a way to set the "Sport" mode so it defaults to ON? So it's on when you first start the car?
Thanks!
Hank

For your second question; you cannot, that's not possible.

There is a guy who does a mod to the center button console that SPORT can be default ON. Same with PSE too.
Has a module you can purchase.

Honestly, I don't know exactly how to get to the symposer port on a Cab. But I can't imagine that it is in any other location than on all other 991s, because the hose running from the engine bay is the same (ie I don't recall ever seeing a separate part or assembly for Cab cars). You don't have to tear anything apart to take a look back there for the small black opening behind the sound deadening materials in the cab... Might be harder to locate because of all the other stuff back there, but get a good flashlight and hunt -- you are bound to find it easy enough....
Once you find it, if you'd like to plug or disconnect the "acoustic simulator" check out this DIY thread on 6Speed.... Even if you don't find the port from the interior side, you can identify it's location from the engine bay.... AND, let's not forget that the symposer is activated via one of our infamous Change Over Valves! In other words, you can simply disconnect the actuator.

Good Luck!

Not that I want to do it, but I had wondered about for those that did just unplugging the valve too. However, the PSE exhaust valves are normally open (loud) when you unplug the changeover right? So if that holds true here unplugging it would cause it to always be on/loud. You'd have to patch the vacuum around the change-over-valve if that is the case. Maybe you or someone knows definitively? In either case it would be fairly simple and likely more effective that trying to stuff things into the port in the car.

Here's info I found in a post from a few years ago. Question answered:
A helpful Rennlister has already explained how to modify the sound symposer in the coupe. The sound inlet is mounted differently in the cab. In the drop-top, you just need to raise the tonneau cover (hold "roof open" button for 4 secs) to reveal the space behind the seats into which the roof folds. Pull off the seal at the back (forward of the engine cover) to release its grip on the plastic mat (forward of the seal). Lift the mat from the nearside rear quarter and find the sound inlet just right of centre. A little heat- and fire-proof insulation, laid over the inlet would presumably achieve the same end.

Hmm, I'm gonna check this out soon. I want to see how much noise is the symposer and how much is actual exhaust!

Additionally - the COV's on the exhaust do fail so I'd be reluctant to leave them open all of the time.
Auto Sport/Sport+ would be nice but not 200 bucks nice to me.
