Hi, My 99 Blazer has noise in exhaust system? mostly when I let up on gas at 50-65 mph. Took it to dealer and was told they heard noise and there were a couple of bulletins from GM on "possible" causes and/or solutions. One is a $300 shield the other a $167 hangar and there is NO guarantee either will work. They would not give any other help. I found
3 GM bulletin numbers on exhaust but don't know how to get more info. from the numbers. If anyone has had this problem or can tell me how to get an explanation of the bulletin number I would really appreciate your help. Thanks ,Ray- posted
