   Torque: 8.5 N*m (87 kgf*cm, 75 in.*lbf) 

Refer to PROCEDURE - Step 16

Refer to PROCEDURE - Step 4

1. Install a new gasket to the front exhaust pipe assembly.
2. Install the front exhaust pipe assembly to the exhaust manifold sub-assembly LH (TWC: Front Catalyst) with the 2 nuts.

   Torque: 56 N*m (571 kgf*cm, 41 ft.*lbf) 

3. Connect the heated oxygen sensor (for Bank 2) connector.
4. Engage the 3 wire harnesses clamps.

1. Install the No. 1 exhaust pipe support bracket with the 2 bolts.

   Torque: 22 N*m (224 kgf*cm, 16 ft.*lbf) 

1. Install a new exhaust manifold to head gasket to the cylinder head sub-assembly.

1. Using a 12 mm deep socket wrench, install the exhaust manifold sub-assembly RH (TWC: Front Catalyst) with the 6 nuts.

   Torque: 21 N*m (214 kgf*cm, 15 ft.*lbf) 

2. Engage the wire harness clamp.
3. Connect the air fuel ratio sensor (for Bank 1) connector.

1. Install the manifold stay to the exhaust manifold sub-assembly RH (TWC: Front Catalyst) and automatic transaxle assembly with bolt and nut.

   Bolt 

   Torque: 34 N*m (347 kgf*cm, 25 ft.*lbf) 

   Nut 

   Torque: 35 N*m (357 kgf*cm, 26 ft.*lbf) 

1. Using a vernier caliper, measure the free length of the compression springs.

   Minimum

   41.5 mm (1.63 in.)

   If the free length is less than minimum, replace the compression spring.

2. Temporarily install a new gasket to the front No. 3 exhaust pipe sub-assembly (center exhaust pipe assembly (TWC: Rear Catalyst) side).
3. Using a plastic hammer and wooden block, tap in the gasket until its surface is flush with the front No. 3 exhaust pipe sub-assembly.

   NOTE:

   • Be careful with the installation direction of the gasket.
   • Do not reuse the gasket.
   • Do not damage the gasket.
   • Do not push in the gasket by using the exhaust pipe when connecting it.
4. Install 2 new gaskets to the front No. 3 exhaust pipe sub-assembly.
5. Temporarily install the front No. 3 exhaust pipe sub-assembly with the 4 bolts, 2 nuts and 2 compression springs.
6. Tighten the 2 bolts and 2 nuts.

   Torque: 56 N*m (571 kgf*cm, 41 ft.*lbf) 

7. Tighten the 2 bolts and 2 compression springs.
