| What do you mean by fluttering sound? Does your exhaust note change tones for a second then back to normal? Sent from my Autoguide app.

| Did you figure this out yet? Mine just started making a "fluttering" sound that fades in and out but only when driving down the road at speeds between 40-75 mph.
