Front Pipe

The installation process for front exhaust pipes begins with spring measurement with a vernier caliper followed by replacement when the measurement falls below the minimum threshold. A new gasket should be fully inserted into the exhaust manifold before using a plastic hammer and wooden block to tap it into correct position and verify that it has the same manifold height without damaging or reusing the gasket. It is essential to prevent using the exhaust pipe for gasket insertion. Secure the front exhaust pipe assembly to the 2 exhaust pipe supports through the application of 2 bolts and 2 compression springs which need installation torque to 43 Nm (440 kgf-cm, 32 ft-lbf). The heated oxygen sensor needs installation according to manufacturer instructions. The assembly of tail exhaust pipe requires checking the compression spring free length before performing replacement if needed. The front exhaust pipe assembly requires a fresh gasket insertion with protocols for correct placement and no reuse and no damage to the components. The 2 exhaust pipe supports require the tail exhaust pipe assembly connection with 2 bolts and 2 compression springs that need to be torqued to 43 Nm (440 kgf-cm, 32 ft-lbf). The final examination includes checking for exhaust gas leakages.

Detach the tail exhaust pipe assembly by removing the 2 bolts and 2 compression springs.

Begin by measuring the free length of the compression spring with a vernier caliper; if it is less than the minimum, replace it.
