Installing

1. Install rear mufflers with new seals. The seals between the exhaust turbochargers and the rear muffler must be replaced. Move the rear muffler into installation position and push the two tensioning straps over the holder on the engine carrier. Then slightly tighten the two hexagon socket head bolts.






2. Screw down the rear muffler on the exhaust catalytic converters. To do this, replace the four M8 fastening nuts on the turbocharger flange on the left and right of the vehicle and tighten to 30 Nm (22 ft. lbs).






3. Tighten tensioning straps. Centre the rear muffler and align free of tension. Tighten the two M6 hexagon socket screws to 15 Nm (11 ft. lbs).
4. Connect oxygen sensors Reconnect the four oxygen sensor cables and clip them in.
5. Install bumpers, centre heat shield and rear spoiler. Check exhaust system for leaks.

Tightening torque:
M8 screw connection on turbocharger flange 30 Nm (22 ft. lbs.)
M6 retaining strap on rear muffler 15 Nm (11 ft. lbs.)
