2017 GT Premium 30,000 mi vibration during slow sharp left and right turns . Feels like from underneath have Magnaflow 3" Catback exhaust installed couple years ago.
If anyone interested the exhaust I thought was vibrating was secure , found it was the differential . Shop strained the fluid no debris was seen refilled with Red Line synthetic and Motorcraft additive. Did a few slow figure 8's then 100 mile road trip so far no noise or vibration
