Procedure D - Remove Front Exhaust Pipe/Inspect Catalyst Lower Surface

Procedure D - Remove Front Exhaust Pipe/inspect Catalyst Lower Surface:





1. Remove the two nuts that secure the Front Exhaust Pipe to the Exhaust Manifold/Catalyst (see Figure D1). Discard the old gasket as you'll be installing a new one later.

NOTE:
The stud(s) may come out of the Catalyst when removing the nut - this is okay. Just re-install them later.





2. Remove the two nuts that secure the Front Exhaust Pipe to the Muffler (see Figure D2). Then, separate the Front Exhaust Pipe from the Muffler. Save the gasket; you'll need to re-use it.





3. This Step For Altima ONLY: Slide the Front Exhaust Pipe Hanger Pin out of the Front Exhaust Pipe Hanger (see Figure D3).

4. Remove the Exhaust Pipe from the vehicle.





5. Inspect the entire catalyst lower surface condition as shown in Figure D4.

IMPORTANT:
Make sure you inspect the entire lower surface. You are looking for cracks or holes in the lower surface.
