Noisy Exhaust Help
I moved from the US to Japan with the Army and brought my W222 S63. Japan noise regulations at full throttle needs to be at or below 85 dB. Anyone have any ideas on what I can do to reduce the decibels, tried packing the muffler with steel wool as a temporary solution but it still fails the test.
