Exhaust System: Service and Repair

Exhaust System Alignment - Gasoline Engines

1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to Vehicle Jacking and Lifting.

2. Loosen all fasteners joining the exhaust system components.

3. Beginning at the front of the vehicle, align the exhaust system to establish the maximum clearance. Make sure all fit pipes are pushed all the way into the preceding pipe and the notches are correctly lined up with the tabs.





4. Align the Y-pipe outlet and tighten the catalytic converter-to-exhaust manifold nuts to specification as follows:
- Tighten the RH leg of the Y-pipe. Tighten the outboard exhaust manifold stud-to-Y-pipe nut to 20 Nm (177 lb-in). Tighten the inboard exhaust manifold stud-to-Y-pipe nut to 40 Nm (30 lb-ft), then tighten the outboard exhaust manifold stud-to-Y-pipe nut to 40 Nm (30 lb-ft).

- Tighten the LH leg of the Y-pipe. Tighten the outboard exhaust manifold stud-to-Y-pipe nut to 20 Nm (177 lb-in). Tighten the inboard exhaust manifold stud-to-Y-pipe nut to 40 Nm (30 lb-ft), then tighten the outboard exhaust manifold stud-to-Y-pipe nut to 40 Nm (30 lb-ft).

5. Align the Y-pipe flange to catalytic converter or catalytic converter delete pipe flare.
- Tighten to 40 Nm (30 lb-ft).

6. Make sure the catalytic converter or catalytic converter delete pipe button is fully inserted into the button slot on the muffler and tail pipe or, if equipped, the exhaust intermediate pipe; then tighten the catalytic converter or catalytic converter delete pipe-to-muffler Torca(R) clamp or, if equipped, the exhaust intermediate pipe Torca(R) clamp.
- Tighten to 55 Nm (41 lb-ft).





7. If equipped, make sure the button on the exhaust intermediate pipe is fully inserted into the button slot on the muffler and tail pipe, and tighten the muffler and tail pipe-to-exhaust intermediate pipe Torca(R) clamp.
- Tighten to 55 Nm (41 lb-ft).





8. Start the engine and check the exhaust system for leaks.
