Muffler: Service and Repair
Mid Muffler Replacement
Mid Muffler Replacement
Replacement Procedure
Important: The entire exhaust system must be removed in order to separate the center muffler from the front exhaust pipe. This reduces
damage to the flexpipe.
The front exhaust pipe must be secured so it does not sag. A bend in the flexpipe of as little as 10-15 degrees can cause damage resulting in
complete malfunction of the flexpipe.
Replace the exhaust manifold. Refer to Exhaust Manifold Replacement (See: Exhaust Manifold/Service and Repair).
