My "new to me" 2015 Fiesta st mk7 have some weird "droning" deep bass frequency in second gear at 1200-2000 rpms when going off throttle. Not sure if is expected. Exhaust is stock

Also, there's a bit of whining noise at high speed when going off throttle, like barely noticeable, that sounds like is coming from the engine bay. Symposer failing?
