Attention! Before proceeding with the repair, make sure that the elements of the system are not hot.
Removing
1. We prepare the car for work (see "Preparing the car for maintenance and repair").
2. Disconnect the additional muffler from the main (see above, "Silencer - replacement").
3. On engines 21114 and 21124, disconnect the additional muffler from the exhaust pipe (see "Metal-graphite sealing ring - replacement").
On engines 2111 and 2112 with two keys by 17 mm unscrew the nuts of the coupling bolts and disconnect the additional muffler from the catalytic converter.
4. Remove the additional muffler, removing its brackets from the suspension cushions (see "Silencer suspension pads - replacement").
Installation
Install the additional muffler in reverse order. If necessary, we replace the suspension pads of the additional muffler and the metal-graphite sealing ring of the swivel joint (on engines 21114 and 21124).
