I have the AWE (No DP) on my 2023 ST and have no issues. No drone and its has a deep "growl" sound on startup and then goes to mild once the computer figures out idle. 50-60mph or whatever gear, there is a higher pitch muffler sound but "it is what it is" on a v6 Ecoboost.
Full throttle sounds fantastic and the cabin sound is minimal. Sport mode, downshift has a nice growling/popping noise as well.
....and those tips!
