4. Verify the gap between the RH catalytic converter-to-exhaust intermediate pipe is within specification. The maximum allowable gap is 5 mm (0.20
inch).
5. NOTE: Using an abrasive pad, clean the exhaust coupling surface area of any surface rust.
Slide the exhaust coupler against the button on the exhaust Y-Pipe-dual catalytic converter, then tighten the exhaust coupler bolts using the
following sequence:
^
Tighten the front nut to 47 Nm (35 lb-ft).
^
Tighten the back nut to 47 Nm (35 lb-ft).
^
Tighten the front nut to 47 Nm (35 lb-ft).
6. NOTE: If a new exhaust intermediate pipe-to-muffler assembly Torca(R) clamp is required, a new exhaust intermediate pipe and Torca(R) clamp
assembly must be installed.
Tighten the exhaust intermediate pipe-to-muffler and tailpipe assembly exhaust Torca(R) clamp to 47 Nm (35 lb-ft).
7. Check to see if the exhaust system isolators are at zero load. If the exhaust system isolators are not at zero load, then carry out the exhaust system
