991 Sports exhaust maintenance
Guys - being new to Porsche and my 991.14S, I find myself listening for all sorts of noises, probably unnecessarily. Noticed a mechanical slight noise on activating the sports exhaust, i.e., metal movement. Am aware that there are some form of external actuators that operate the flaps, but was just wondering if this is something that would need lubricated from time to time, and if so, how best to do that? Car has 14k miles.
thanks
thanks

The actuator can be replaced fairly easy, the internal flap is inaccessible

If you do choose to put a dry high-temp lube on the ball or the butterfly's pivot I think you'd be fine. But I'd be careful not to get lube inside the actuator as it may harm the integrity of the seals or diaphragm.
