The occurrence of exhaust leakage or abnormal
noise is caused by cracks or strain in the gasket, or
by when the exhaust pipe or muffler is damaged due
to impacts during travel. The exhaust leaks from
these sections and causes the exhaust noise to
increase. There may be cases when there is
interference with the body and vibration noise is
generated.
