SERVICE INFORMATION:
Some customers may complain of a loud exhaust resonance noise at high engine R.P.M.s. It has been determined that the noise is emitted from the
muffler. A countermeasure muffler has been developed with an inner structure modified to reduce the resonance noise. Additionally, during production
an improved process was incorporated to reduce the possibility of the black paint on the rear face of the muffler from peeling.
