INSTALLATION

1. INSTALL EXHAUST PIPE ASSEMBLY FRONT
(a) Install a new gasket onto the exhaust manifold RH.
(b) Install the exhaust front pipe with the new 2 nuts.
Torque: 62 Nm (632 kgf-cm, 46 ft-lbf)
2. INSTALL EXHAUST FRONT PIPE ASSEMBLY NO.2
(a) Install a new gasket onto the exhaust manifold LH.
(b) Install a new gasket onto the exhaust front pipe.
(c) Install the exhaust front pipe No. 2 onto the insulator.
(d) Install the exhaust front pipe No. 2 onto the exhaust manifold LH with the new 2 nuts.
Torque: 62 Nm (632 kgf-cm, 46 ft-lbf)
(e) Install the exhaust front pipe No. 2 onto the exhaust front pipe with the 2 bolts and 2 nuts.
Torque: 48 Nm (489 kgf-cm, 35 ft-lbf)





(f) Install a new gasket onto the exhaust front pipe No. 2.
(1) Using a wooden block and plastic- faced hammer, tap in a new gasket until it is flush with the exhaust front pipe No. 2.

NOTE:
- Make sure that the gasket is in the correct direction when installing.
