The front pipe replacement starts by removing the rear heated Oxygen Sensor before you can access the connecting pipe mounting bracket bolt at the next step. Finally you will need to separate the connecting pipe nuts along with its gasket from the Catalytic Converter. Clean the seal surfaces by removing all nuts that connect between the front muffler pipe and the connecting pipe. Identify any holes or damage as well as open streams or deterioration zones that might permit exhaust fumes to infiltrate the passenger space on the connecting pipe. The Catalytic Converter and connecting pipe with gasket need to connect to the front muffler pipe flange then tighten the nuts to 30 n.m (22 lb ft). Fasten the connecting pipe to the Catalytic Converter by applying nuts and the gasket and tighten these nuts until they reach 40 n.m (30 lb ft). Thank your installation process ends with installing the front Exhaust Pipe mounting bracket bolt at 40 n.m (30 lb ft) torque and reinstallation of the rear heated Oxygen Sensor held with 41 n.m (30 lb ft) torque.

First of all, the nuts and the gasket from the front Muffler pipe to the connecting pipe flange, then the nuts and the gasket from the rear Muffler pipe flange should be removed, clearly to replace the front Muffler. Take off the front Muffler from the rubber hanger and pull the front Muffler out. Check the Exhaust Pipe and the front Muffler for any hole or damage or open seam or deterioration which may cause the exhaust fumes to enter in to passengers compartment or trunk. For installation to the rubber hanger which is relocated on the end of the front Muffler to secure it. Then attaching the mutter at the rear img Muffler and the gasket with the nuts, placing the front Muffler to be secured with the rubber off the rubber hanger. Tighten the front Muffler-to-rear Muffler nuts to 30 n.m (22 lb ft). Loosely clamp the front Muffler assembly to the apex of the connecting pipe flange, then tighten front Muffler-to-connecting pipe nuts to 30 n.m (22 lb ft).

Secure it with the nuts, tightening the front muffler-to-connecting pipe nuts to 30 Nm (22 ft. lbs.).

Inspect the rear muffler and the pipe for holes, damage, open seams, and other deterioration that could allow exhaust fumes to enter the passenger compartment or trunk.

Attach the catalytic converter and connecting pipe along with the gasket to the front muffler pipe flange, securing them with nuts tightened to 30 Nm (22 ft. lbs.).

Secure the rear muffler assembly to the rubber hangers on the tail pipe end.

Connect the front muffler to the rubber hanger.

Install the front exhaust pipe mounting bracket bolt and tighten it to 40 N.m (30 lb ft).
