You will need: a 13 mm wrench and a flat-blade screwdriver.
1. Disconnect the flanges of the exhaust manifold and the additional muffler (see "Removing, installing the exhaust manifold and replacing its gasket").
2. Remove the cushions from the brackets at the rear of the main muffler…
3. …and the exhaust pipe, and then remove the main and additional mufflers from the car.
NOTE: The front main muffler suspension cushion was removed from its bracket before separating the exhaust manifold and sub-muffler flanges (see item 1).
4. Install the main and additional mufflers in the reverse order of removal. Be sure to replace the sealing gasket between the flanges of the exhaust manifold and the additional muffler with a new one. To facilitate the installation of the suspension cushions, lubricate the brackets of the main muffler and exhaust pipe with a soap solution.
NOTE: The main and additional mufflers with pipes can be supplied separately as spare parts. The pipes can have a flared end of increased diameter for a telescopic connection or not have a flared end for a butt connection. In both cases, to replace the damaged element, it is necessary to cut the connecting pipe on site, for example, with a surface grinder ("Bulgarian"), placing a new element nearby to determine the place of the cut. Moreover, for a telescopic connection, it is necessary to cut the pipe with a margin necessary for inserting the old pipe into the new one, and for a butt connection - without a margin. In the first case, the pipes are connected using a clamp, and in the second - by welding or a transition coupling.
