have a 2019 991.2 gts which I am loving. Great drive, and great exhaust note then yesterday I took it to a do it yourself car wahs and one of metal drain gates on the ground was placed wrong and it may have scraped the bottom of my car as I heard a noise. Now it seems like the over run cracks and pops are not as often and more quiet when the car is in sport mode. It seems that the exhaust valves are working as the exhaust will change tone when I push the exhaust button. Does anyone know if I messed something up or what would be going on? Any in site is much appreciated!
