newby question on exhaust sound
I have a S without PSE (for now)
I noticed that the exhaust got this loud cracking sound when you let off the gas after revving. I am guess is normal 911 exhaust and what i am hearing is the backfire sound. (esp after listening to sound sound clips on youtube)
If that's how is suppose to sound on the 911....feel free to LAUGH!!! :-D

It is called overrun in this case and yes it is an engineered-in "feature" that is either loved or not. Even without PSE you can hear it if the car has Sport Chrono and is in one of the sport modes (but not Sport Plus in a 991.2).

Lol normal it is thanks!
no i am not in sport mode. I notice this when i am sitting still and revving the engine. When the rpm drops to about 2k i can hear the chatter/cracking sound. I do have SC in a pdk
just want to make sure everything is good before installing in the PSE.
