991 Cab sound symposium fix.

[David W.]

This on a 991.1.
For anyone that likes the responsiveness of sport mode but gets bored with the extra noise I did the 5 minute fix this morning as found on other forums.
Raise rear deck lid.
Pull back carpet from under the rubber strip to expose the hole.
Some high density foam cut to shape then inserted using a screwdriver to force it in for a good fit.
I looped some string around the bottom for easier removal.
Quick test drive proved it worked very well.
