   Align the cutout of a new tail exhaust pipe baffle sub-assembly with the protrusion (for position alignment) of the tail exhaust pipe assembly as shown in the illustration.

2. Insert the tail exhaust pipe baffle sub-assembly to the position where it can be pressed in by hand.
3. Using a plastic hammer and wooden block, uniformly tap the tail exhaust pipe baffle sub-assembly onto the tail exhaust pipe assembly.
   NOTE:

   • Lightly tap the top and bottom of the tail exhaust pipe baffle sub-assembly so that the tail exhaust pipe baffle sub-assembly is pressed in without a tilt.
   • Press the tail exhaust pipe baffle sub-assembly in until the protrusion (for stopper) on the tail exhaust pipe baffle sub-assembly is fit into the cutout area of the tail exhaust pipe baffle sub-assembly.
   • Check that there is no looseness in the tail exhaust pipe baffle sub-assembly.

1. Install a new gasket to the front exhaust pipe assembly (TWC: Rear Catalyst).
2. Connect the front exhaust pipe assembly (TWC: Rear Catalyst) to the 2 exhaust pipe supports.
