GLE350 Exhaust Noise Solution
I recently purchased a 2017 GLE350. With the new car excitement, at first I failed to notice the annoying exhaust whine or moan at 1500 rpm. But when I did I felt I could not live with it. The dealership was no help and refused to concede that the car had a problem. Back at home I looked under the car and immediately deduced that the problem would be easy to solve. So with a little roofing flashing, two large hose clamps and ten minutes of time I cured my moaning GLE. The finished project is not the best looking thing but the car sounds perfect now.
The solution was to roll up about a 9" x 10" piece of aluminum flashing and slide it into the fake exhaust port from the outside. Then slide it on to the exhaust pipe and clamp it tight with the hose clamp. It may need to be adjusted to looked good. Then do the other side. See the attached pictures. I plan to take the car to a muffler shop and have a professional job done.
