- With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to JACKING AND LIFTING article.
- Loosen all fasteners joining the exhaust system components.
- Beginning at the rear 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.
- Align the converter Y-pipe flange-to-resonator and muffler inlet pipe.
- 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 (15 lb-ft). 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 (15 lb-ft). 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).
- Make sure that the tab on the extension pipe is seated inside the notch on the muffler outlet pipe before tightening the exhaust clamp.
- Tighten clamps to specification. For additional information, refer to Specifications in this article.
- Start the engine and check the exhaust system for leaks.
