Installing Rear Muffler

Information 

• Due to manufacturing problems, rear mufflers (rear silencers) with non-standard exhaust pipe lengths will be delivered as spare parts during the first 3 - 6 months. 
• These spare parts must be adapted until such a time as the standard spare parts are introduced. 
• The cutting positions are marked and the parts must be cut at the centre markings. 

1. Adapt non-standard spare parts by shortening the exhaust pipes, making sure to cut according to the markings! 
   1. 1.1 Use the same tools as used for removing the rear silencer  (see removal instructions).
2. Only for vehicles with sports exhaust system:  Install exhaust flap actuator on the new rear silencer.
