The purpose of this bulletin is to make available the part numbers for exhaust mufflers for service. Replacing only the exhaust muffler, instead of the complete exhaust system from the converter back, greatly reduces repair expenses.
Do This | Don't Do This |
|---|---|
Replace only the muffler. | Do not replace the exhaust system rear of the converter if only a service muffler is needed. |
