Note: All elements of the exhaust system are connected by threaded connections and can be removed separately. When removing, the self-locking nuts and gaskets must be replaced.
Removal
Raise the car, see item 29.
Spray all muffler mounting bolts and nuts, as well as connection points, with rust solvent. Allow the rust solvent some time to act.
Unscrew or disconnect all muffler parts in the sequence shown in the figure.
The non-removable parts of the muffler should be supported or suspended with wire from the body.
Attention: When removing and installing the catalytic converter, protect it from impacts, as it may be damaged. That is, do not drop it or hit the housing with a hammer.
Installation
Note: To facilitate removal and unscrewing in the future, it is recommended to coat the nuts and bolts with a high-temperature paste, such as Liqui Moly LM-508-ASC. When installing a used pipe, clean its connection points from combustion residues with sandpaper before installation.
Note: Especially on cars with a catalytic converter, the muffler section before the catalytic converter must be sealed first. Therefore, all removed gaskets must be replaced with new ones, otherwise deterioration in performance may be observed.
Fasten or hang all muffler parts on rubber holders in the reverse order to that shown in the figure. Do not tighten the bolts.
Before tightening the bolts, straighten the muffler pipes by moving and turning them and hang them on rubber hangers. At the same time, ensure sufficient distance from the bottom (at least 25 mm).
Tighten the mounting flanges to the tightening torques shown in the figure.
Caution: Do not overtighten the bolts, otherwise the gaskets will become deformed, which will cause leaks in the system.
Lower the car, see item 29.
