Warning
Danger of burns The exhaust system gets very hot when the vehicle is driven.
– Allow the exhaust system to cool down before performing any work on the vehicle.
Info
Over time, the fibers of the rock wool escape into the air, and the main silencer "burns out".
Not only is the noise level higher, the performance characteristic changes.
Preparatory work
– Remove the main silencer. ( p. 65)
