General information
1. Depending on the model, the exhaust system consists of two or three sections. The two-section system consists of a receiving pipe and a rear pipe. The three-section system consists of a downpipe, an intermediate pipe and a rear pipe. The three-section system also includes a catalytic converter, which is integrated with the downpipe and intermediate pipe.
2. The sections of the exhaust system are connected either by means of clamps with spring-loaded balls (which allows for some mobility of the exhaust system), or using a clamping ring.
3. The system is suspended along its entire length using rubber supports.
4. Each section can be removed individually or, alternatively, the entire system can be removed. Even if only one part of the system requires attention, it is often easier to remove the entire system and separate the sections on the bench.
5. To remove the system or part of the system, first raise the front or rear of the vehicle and place secure supports underneath it (see "Lifting and installing the car on supports"). Alternatively, place the car over an inspection pit or lift it onto an overpass.
Downpipe
6. On 1.9L and early 2.0L models, remove the nuts on the flange connection between the downpipe and manifold and remove the spring caps and springs. Remove the bolts and wire mesh gasket. On later models with the 2.0L engine, remove the nut, washer and bolt in the bolted joint on the clamp ring and remove the clamp ring from the turbocharger flange joint.
7. Ask an assistant to support the front end of the pipe, and then unscrew the nut, remove the washer and remove the bolt in the bolted joint on the clamp ring and remove the clamp ring from the flange joint.
8. Release the pipe from the rubber support(s) and remove it from under the vehicle.
Intermediate pipe
9. Loosen the nuts, remove the washers and remove the bolts in the bolted connections on both clamping rings and remove both clamping rings from the flange connections.
10. Release the pipe from the rubber support and remove it from under the car.

Rear pipe
11. Loosen the nut, remove the washer and remove the bolt in the bolted connection on the clamping ring and remove the clamping ring from the flange connection.
12. Release the rear pipe from the corresponding rubber supports and remove it from the vehicle.
Complete system
13. Separate the downpipe from the manifold/turbocharger as described above.
14. Call an assistant, release the system from all rubber supports and remove it from under the car. Remove the wire mesh gasket from the manifold joint (if applicable).
Heat shield
15. Heat shields are secured to the underbody of the vehicle using various nuts and bolts. If the screen is removed to gain access to components located behind it, remove the nuts and/or fasteners (to do this, unscrew the central screw and then remove the entire retainer) and then remove the screen. On some models, it may be necessary to release the exhaust system from its mountings to allow removal of the large heat shield.
Installation
16. Each section is installed in the reverse order of removal, taking into account the following points:
- a) Remove all traces of corrosion from the flanges and replace all necessary gaskets.
- b) Inspect the rubber mounts for signs of damage or deterioration and replace if necessary.
- c) If the connection uses a clamping ring, apply exhaust system assembly paste to the flange connection to ensure a gas-tight joint.
- d) Before tightening the exhaust system bolts/nuts, make sure that all rubber mounts are correctly positioned and that there is sufficient clearance between the exhaust system and the underbody of the vehicle.
