How to replace the muffler on 4.3L, 4.8L, 5.3L, and 6.0L engines on Chevrolet Express 2500?

Wear protective goggles and gloves when replacing the Muffler systems on vehicles powered by 4.3l, 4.8l, 5.3l, or 6.0l engines and observe exhaust service security protocols. Muffler replacements happen as one complete system with Exhaust Pipe and Tail Pipe with aftermarket tail pipes existing in some vehicles. Start the procedure by lifting the frame which lowers the rear axle position. You need to disconnect the nuts from the Catalytic Converter pipe flange on a 4.3l-single-pipe setup to access it. For 4.8l, 5.3l or 6.0l engines utilizing dual Catalytic Converter pipes, start by loosening the right clamp and unfastening the left Catalytic Converter nuts at the Muffler flange. Two people might be needed to remove exhaust hanger insulator pins because of their weight unless the vehicle's wheelbase matches the exhaust system's length precisely. Manually lift the Muffler assembly above the rear axle before removing it in the direction of the vehicle front. During installation you need two people to position the Muffler assembly from the front of the vehicle and lift it over the rear axle. Fasten the Muffler assembly hanger pins to the exhaust hanger insulators. To install the retaining nuts and new gasket on the front of the Muffler you need to properly tighten the Catalytic Converter to Muffler retaining nuts using 48 n.m (35 lb ft). Right catalytic converters for 4.8l 4.3l and 6.0l engines need to be installed within the Muffler followed by a clamp nut torque to 54 n.m (40 lb ft). When installing the left Catalytic Converter to the Muffler flange use a new gasket while tightening the retaining nuts to 48 n.m (35 lb ft) to achieve proper exhaust system alignment; proceed by tightening the right Catalytic Converter clamp to 54 n.m (40 lb ft) and the left Catalytic Converter to Muffler flange nuts also to 48 n.m (35 lb ft). Finally, lower the vehicle.
