5. REMOVE EXHAUST PIPE ASSY TAIL
a) Remove the exhaust tail pipe with 2 bolts and 2 springs.
6. REMOVE FLOOR PANEL BRACE FRONT





a) Remove 2 nuts and the floor panel brace.
7. REMOVE EXHAUST PIPE ASSY FRONT
a) Remove 2 bolts, 2 springs and exhaust front pipe.
8. INSTALL EXHAUST PIPE ASSY FRONT
a) Check the free length.





1) Using vernier calipers, measure the free length of the compression spring.
Minimum length: 41.5 mm (1.6339 inch)

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





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

NOTICE:
^ Make sure that the gasket is installed in the right direction.
^ Do not reuse the removed gasket.
^ Never push the gasket into the exhaust manifold by installing the exhaust pipe front onto the exhaust manifold.

c) Install the exhaust pipe front onto the 2 exhaust pipe supports No. 4.
d) Tighten the 2 compression springs and 2 bolts.
Torque: 43 Nm (440 kgf-cm, 32 ft. lbs.)
9. INSTALL FLOOR PANEL BRACE FRONT
a) Install the floor panel brace with 2 nuts.
Torque: 30 Nm (302 kgf-cm, 22 ft. lbs.)
10. INSTALL EXHAUST PIPE ASSY TAIL
a) Check the free length.





1) Using vernier calipers, measure the free length of the compression spring.
Minimum: 38.5 mm (1.5158 inch)
If the free length is less than minimum, replace the compression spring.





b) Install a new gasket onto the exhaust pipe front.

NOTICE:
^ Make sure that the gasket is installed in the right direction.
^ Do not reuse the removed gasket.
^ Never push the gasket into the exhaust pipe front by installing the exhaust pipe tail onto the exhaust pipe front.

c) Install the exhaust pipe tail onto the 3 exhaust pipe supports No. 4.
d) Tighten the 2 compression springs and 2 bolts.
Torque: 43 Nm (440 kgf-cm, 32 ft. lbs.)
11. INSTALL HEATED OXYGEN SENSOR (BANK1, SENSOR2 OXYGEN SENSOR)





a) Using SST, install the heated oxygen sensor.
SST 09224-00010
Torque: 44 Nm (450 kgf-cm, 33 ft. lbs.)
b) Connect the heated oxygen sensor connector.

HINT: After installing heated oxygen sensor, check that sensor wire is not twisted. If it is twisted, remove heated oxygen sensor and reinstall it.

12. INSTALL HEATED OXYGEN SENSOR (BANK1, SENSOR1 OXYGEN SENSOR)





a) Using SST, install the heated oxygen sensor.
SST 09224-00010
Torque: 44 Nm (450 kgf-cm, 33 ft. lbs.)
b) Connect the heated oxygen sensor connector.

HINT: After installing heated oxygen sensor, check that sensor wire is not twisted. If it is twisted, remove heated oxygen sensor and reinstall it

13. INSTALL CONSOLE BOX ASSY REAR
14. CONNECT BATTERY NEGATIVE TERMINAL
Torque: 5.4 Nm (55 kgf-cm, 48 inch lbs.)
15. CHECK FOR EXHAUST GAS LEAKAGE
