How is the muffler serviced as a complete assembly on 2007 Chevrolet Impala?

It is serviced as a whole assembly that can hardly be serviced separately. Take out the Catalytic Converter, then ask for an assistant to hold the Muffler assembly while you disconnect it from the exhaust insulators. Make sure that the mating surfaces of the Catalytic Converter and Muffler are cleaned. For installation, lubricate the insulators with spray lubricant, followed by helping to mount the Muffler assembly onto the exhaust insulators before fitting the Catalytic Converter.
