Before it becomes possible to replace the exhaust Muffler with lfa, the vehicle must be raised and supported first. No description available. Lubricate the insulators where the Muffler pipe hangers are to be placed to allow for easy removal of the insulators on the exhaust system hangers (1, 2 and 3). This will require help, remove the Muffler pipe assembly from the vehicle. For installation, lubricate the insulators once more to ease installation and with aid, install the Muffler pipe assembly to the exhaust system hangers (1, 2, and 3). Mount the Muffler assembly to the resonator, making sure the Muffler assembly is positioned to the three-way Catalytic Converter clamp bolt and tighten it to 44 nm (32 lb ft). Lastly, but not least, reduce the vehicle and check the exhaust system for leaks.
