Removing
1. We install the car on a viewing hole or overpass (see "Vehicle preparation for maintenance and repair").
2. Disconnect the converter from the exhaust pipe (see "Downpipe - removal and installation").
3. Using a 17 mm spanner, unscrew the two bolts securing the flanges of the converter and the additional muffler, holding the nuts from turning with a wrench of the same size.
4. Remove the converter.
Installation
We install the converter in the reverse order, applying graphite grease to the threads of the bolts.
