I know there was a thread some time ago with owners of 13/14's complaining about a howl they can hear in 6th gear at constant cruising speeds, that would immediately go away as soon as their foot was lifted off the gas pedal, and come back as soon as the gas pedal was engaged again. Mine has been doing it since new. Did anyone with this problem ever get it fixed? My car is in the shop now for some warranty work, and I had them check that out. They verified the sound, then tried to say it was my aftermarket exhaust, which is complete BS.
