Exhaust Pipe: Service and Repair

AFTER SILENCER/TAILPIPE REPLACEMENT [LF, L3]

California Emission Regulation Applicable Model

NOTE:
- The after silencer is integrated with the presilencer and main silencer. Therefore, when replacing the after silencer, cut between the main silencer and after silencer.
- After bending the body insulator to secure a work space, return it to its original condition after the installation.
- After the installation, verify that there is no noise.
Cut Location

CAUTION:
- Be careful not to deform the pipe when cutting. If the pipe is deformed, the new pipe may not be installed correctly.

1. Remove three rubber hangers from back side.

2. Cut the pipe between the main silencer and after silencer using the following procedure. (Cut location B)
NOTE:
- Perform measurement parallel to the pipe being cut.

a. Measure the length from the hanger inner edge at the end.

b. Cut the pipe at the specified location.

3. Remove burrs from the cut surface on the main silencer side using a round file.

4. Install the new after silencer to the main silencer using the following procedure. (Cut location B)
a. Measure the indicated length from the cut surface of the new after silencer to the marking.

b. Apply heat-resistant sealant to the specified position along the complete perimeter.

c. Insert the U-shaped bolt.

d. Insert the joint pipe to the main silencer.

e. Insert the after silencer to the joint pipe.

f. Secure the exhaust pipe to the rubber hanger.

g. Align the cut surface of the joint pipe with the marking.

h. Verify that the exhaust pipe is installed without any bends or strain on the pipe.

5. Tighten the U-shaped bolt between the main silencer and the new after silencer using the following procedure. (Cut location B)
NOTE:
- The joint pipe has a marked line at the specified position where the U-shaped bolt is to be set.

a. Set the U-shaped bolt in the specified position.

b. Set the U-shaped bolt so that it faces the vehicle lower side.

CAUTION:
- Do not loosen U-shaped bolt after tightening. If it is loosened, the bolt cannot be tightened at the specified torque with the specified protrusion.
- Tighten the U-shaped bolt in three or four steps, left and right equally, to prevent clamp deformation.

NOTE:
- Tighten the U-shaped bolt on the main silencer side first, then the after silencer side.

c. Tighten the U-shaped bolt on the main silencer side.

Protrusion of U-shaped bolt after tightening
- 3-7 mm {0.12-0.27 in}

d. Gradually tighten the U-shaped bolt on the after silencer side verifying that the after silencer end is at the center of the bumper as viewed from behind the vehicle.

Protrusion of U-shaped bolt after tightening
- 3-7 mm {0.12-0.27 in}

6. Start the engine, and verify that there is no noise.

Except for California Emission Regulation Applicable Model

NOTE:
- The tailpipe is integrated with the presilencer and main silencer. Therefore, when replacing the tailpipe, cut between the main silencer and tailpipe.
