| 09-66-16 | 2017-08-14. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:MANIFOLD/HEADER/MUFFLER/TAIL PIPE. 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. |
