I should say that any other time without MDS the system sounds good, if not loud but I work 3rd shift and I can't idle my truck in the driveway with the remote start without being an a$$hole to the neighbors.
many members here have reported that leaving the stock resonators on with an aftermarket muffler eliminates the drone.
