991 Sound Synthesizer

[eric1000]

I have just plugged the sound synthesizer output into the cabin of my 991 and got rid of the (to me) horrible speed related drone. It allows me to hear the relatively quiet engine/exhaust sound which is much more pleasant.
Next stop a louder exhaust......

It’s a tube that runs from the engine compartment to the rear of the cabin.
