Tail Pipe

A vehicle placed on a hoist in NEUTRAL driving position needs to be used for exhaust Y-pipe dual catalytic converter servicing. You should support the exhaust system with a proper jack for the task. Separate the electrical connection of both heated oxygen sensors (HO2S) and catalyst monitor sensors. The process begins by eliminating all hardware components which join the exhaust Y-pipe dual catalytic converter to the muffler assembly including bolts and nuts as well as the gasket. The next procedure requires removal of the transmission support crossmember. Separate the nuts between the exhaust Y-pipe dual catalytic converter and the exhaust manifold for removal before discarding them. Next remove the exhaust Y-pipe dual catalytic converter from its position. Install anti-seize lubricant on the HO2S and catalyst monitor sensor threads before installing them at 40 Nm (30 ft lbs) torque. Position the Y-pipe dual catalytic converter exhaust and use new nuts for its installation to the exhaust manifold. Place a new gasket in addition to bolts and nuts for the exhaust Y-pipe dual catalytic converter to muffler assembly, and install them loosely. Place back the transmission crossmember before you align the vehicle exhaust system and connect power lines to HO2S and catalyst monitor sensors.

Remove the transmission support crossmember and the nuts connecting the exhaust Y-pipe dual catalytic converter to the exhaust manifold, discarding these nuts as well.

Utilize new fasteners with the same part number as the originals and adhere to specified torque values to ensure correct retention of exhaust components.

Tighten to 40 Nm (30 lb-ft).
