Exhaust System

GENERAL INFORMATION

On vehicles without a catalytic converter, the exhaust system consists of 3 sections: the front pipe, the center section with resonator, and the rear section with muffler.

On vehicles with a catalytic converter, the exhaust system consists of 4 sections: the same 3 sections plus the catalytic converter section.

The exhaust pipe is suspended along its entire length on rubber mounts; the pipes are connected by flanges.

Removal Each section can be removed independently of the others. The entire system can also be removed at once.

PROCEDURE

1. Raise the vehicle and support it on stands (or drive onto a pit or lift).

Front Pipe

2. Unscrew the nuts securing the front pipe to the manifold.

3. Unscrew the bolt securing the pipe to the bracket.

4. Disconnect the pipe from the manifold, remove the gasket.

5. Separate the flange connection and remove the pipe and gasket.

Catalytic Converter (on some vehicles)

6. Unscrew the two nuts and two bolts securing the pipe to the catalytic converter.

7. Unscrew the two bolts securing the center pipe to the catalytic converter.

8. Remove the catalytic converter and gaskets.

Center Pipe

9. On vehicles with a catalytic converter, unscrew the two bolts securing the center pipe and remove the gasket.

10. On vehicles without a catalytic converter, unscrew the two nuts and two bolts, remove the springs and disconnect the center pipe from the front pipe. Remove the gasket.

11. On all vehicles, unscrew the bolt of the rubber mount at the rear of the center pipe.

12. Unscrew the bolts securing the center pipe to the muffler tail pipe.

13. Remove the center pipe and gasket.

Rear Muffler Section

14. Unscrew the two bolts securing it to the center pipe.

15. Unhook the straps and remove the section.

Entire System

16. Unscrew the nuts securing the front pipe to the manifold and the bolt securing it to the bracket, disconnect the pipe from the manifold, remove the gasket.

17. With an assistant, detach the system from the rubber mounts and remove it from the vehicle.

Heat Shields

18. Shields are installed on some vehicles and secured with nuts, bolts and clips.

Installation

PROCEDURE

2. Before installation, replace the gaskets and clean the mating surfaces.

3. Check the condition of the mounts and replace if necessary.
