## NHTSA's summary

This bulletin announces a change in the production procedure for the rear muffler assembly. Spot\-weld locations securing the outer shell portion have been changed to improve overall rigidity. A gap may develop at the spot welded seam as a result of repeated thermal shock \(heating / cooling\) which occurs during normal use. The gap does not create an exhaust leak. In some cases, a rattling sound from the muffler may develop.
