The procedure to service and repair the muffler begins with waiting for the exhaust system to cool down because its components especially the three-way catalytic converter achieves high temperatures shortly after the engine starts. The first step starts with taking out the shock absorbers located at the rear of the vehicle while you also need to remove the dual converter assembly flange nuts. You can evacuate the exhaust pipe assembly from its position on the rear exhaust hanger insulator then detach the insulator before removing the muffler. Allowing soaps with water works best to install exhaust hanger insulators since applying oil or grease lubricants can damage the rubber material. The installation procedure runs in reverse order of the uninstallation process.
