How to replace the muffler on a 1500 Series equipped with a 4.3L, 4.8L, 5.3L, or 6.0L engine on 2007 Chevrolet Silverado 1500?

Installation of the new Muffler on 1500 series vehicles starts by supporting the vehicle and lowering the spare tire when replacing engines using 4.3l, 4.8l, 5.3l, and 6.0l as power units. Start by removing the exhaust Muffler nuts which secure the Catalytic Converter. A 4.8l engine requires lubrication on the 3 insulator points entering the Muffler assembly hangers before their removal. With help, personnel can detach the insulators (1, 2) from the front and rear hanger points. Take out the intermediate Muffler assembly by first removing its insulator followed by pulling the assembly backward until the front frame crossmember flange clears. The procedure for insulators (1, 2) lubrication and removal must be repeated exactly as described for vehicles using 5.3l or 6.0l engines. Both flex couple installation and removal require careful handling to avoid damage to internal structures. To install the Muffler assembly with a 4.8l engine system you must perform a new lubrication of the 3 insulators before properly positioning the assembly then assisted installation of the insulators (1, 2) on the front and rear Muffler hangers followed by the insulator installation to the intermediate hanger. The installation procedure should be redone for vehicles equipped with 5.3l or 6.0l engines. Next proceed with installing the Catalytic Converter by attaching exhaust Muffler nuts while torquing to 45 n.m (33 lb ft). Once complete replace the spare tire and lift the vehicle down.
