b) Disconnect the 2 exhaust pipe supports, and remove the tailpipe and gasket.

6. REMOVE FRONT EXHAUST PIPE
a) Disconnect the 2 heated oxygen sensor connectors.
b) Remove the grommet.
c) Remove the 2 bolts and 2 compression springs.
d) Disconnect the 2 exhaust pipe supports, and remove the front exhaust pipe.
e) Remove the gasket from the exhaust manifold.

7. REMOVE HEATED OXYGEN SENSOR (for Bank 1 Sensor 1)

SST 09224-00010

8. REMOVE HEATED OXYGEN SENSOR (for Bank 1 Sensor 2)
a) Using SST, remove the sensor from the front exhaust pipe.
SST 09224-00010

INSTALLATION

1. INSTALL HEATED OXYGEN SENSOR (for Bank 1 Sensor 2)
a) Using SST, install the sensor to the front exhaust pipe.
SST 09224-00010
Torque: 40 Nm (408 kgf-cm, 30 ft. lbs.) for use with SST
44 Nm (449 kgf-cm, 32 ft. lbs.) for use without SST

HINT: Use a torque wrench with a fulcrum length of 30 cm (11.81 inch).

2. REMOVE HEATED OXYGEN SENSOR (for Bank 1 Sensor 1)
a) Using SST, install the sensor to the front exhaust pipe.
SST 09224-00010
Torque: 40 Nm (408 kgf-cm, 30 ft. lbs.) for use with SST
44 Nm (449 kgf-cm, 32 ft. lbs.) for use without SST

HINT: Use a torque wrench with a fulcrum length of 30 cm (11.81 inch).

3. INSTALL FRONT EXHAUST PIPE
a) Using a vernier caliper, measure the free length of the compression spring.
Minimum length: 40.5 mm (1.594 inch)
If the length is less than the minimum, replace the compression spring.

b) Using a plastic-faced hammer and wooden block, tap in a new gasket until its surface is flush with the exhaust manifold.

NOTICE:
^ Tap in the gasket in the correct direction.
^ Do not reuse the removed gasket.
^ Do not to push in the gasket while installing the exhaust pipe.

c) Connect the 2 exhaust pipe supports, and install the exhaust pipe.

d) Install the 2 compression springs and 2 bolts.
Torque: 43 Nm (438 kgf-cm, 32 ft. lbs.)
e) Connect the 2 heated oxygen sensor connectors.
f) Install the grommet.

4. INSTALL TAILPIPE
a) Install a new gasket onto the front exhaust pipe.
b) Connect the 2 exhaust pipe supports, and install the tailpipe.
c) Install the clamp with the bolt as shown in the illustration.
Torque: 32 Nm (326 kgf-cm, 24 ft. lbs.)

5. CHECK FOR EXHAUST GAS LEAKS

6. INSTALL FRONT PANEL BRACE
a) Install the floor panel brace with the 2 bolts.
Torque: 20 Nm (204 kgf-cm, 14 ft. lbs.)

7. INSTALL REAR CONSOLE BOX
8. INSTALL SHIFT LEVER KNOB (for Manual Transaxle)
9. CONNECT CABLE TO NEGATIVE BATTERY TERMINAL
