  1. INSPECT EXHAUST PIPE ASSEMBLY 
    1. Check the connections for looseness or damage.

      If the exhaust pipe is loose, tighten it.

      If damaged, replace it.

    2. Check the clamps for wear, cracks or damage.
  2. INSPECT TWC 

    Check for dents or damage.

    If any part of the protector is damaged or dented for example, the protector comes in contact with the TWC, repair or replace it.

  3. INSPECT HEAT INSULATOR 
    1. Check the heat insulator for damage.

      If the heat insulator is damaged, repair or replace it.

    2. Check that there is adequate clearance between the catalytic converter and heat insulator.

      If there is no clearance, repair or replace the heat insulator.
