The muffler body band clamp blade must be free to move in the hanger or vibrations will be transmitted from the exhaust system into the body. The muffler can be moved both vertically and horizontally in the isolator block. The muffler should move 1/16 in. vertically and 1/8 in. horizontally minimum in the isolator block.NOTE: If muffler movement cannot be obtained, or muffler isolator block is damaged, the exhaust system will have to be carefully lowered for adjustment or replacement of the muffler isolator block.
