- Loosen bolts of double clamps => [ (Item 10) Front clamping sleeve ] Exhaust System Component Overview and => [ (Item 21) Rear clamping sleeve ] Exhaust System Component Overview.
- Push forward part of exhaust system far enough forward - arrow - until pre-load on retaining loops on center muffler - a - = 5 to 9 mm.
- Tighten threaded connections of front double clamps => [ (Item 10) Front clamping sleeve ] Exhaust System Component Overview evenly to 40 Nm.
- Push rear part of exhaust system far enough forward - arrow - until pre-load on retaining loops at rear on rear muffler - a - = 7 to 11 mm.
- Align rear muffler horizontally.
- Tighten threaded connections of rear double clamps => [ (Item 21) Rear clamping sleeve ] Exhaust System Component Overview evenly to 40 Nm.
- Align end pipes.
Tailpipes, aligning
- Check distance of end pipes at left and right to bumper:
• Dimension - x - left = dimension - x - right.
If necessary, correct dimension x as follows:
- Loosen nuts - arrows - of brace between exhaust pipes.
- Adjust distance between the rear mufflers.
- Tighten nut to 25 Nm.
- Check distances - y - and - z - of end pipes to bumper:
• Dimension - y - = greater than 20 mm.
• Dimension - z - = 10 to 16 mm.
- If necessary, check whether the exhaust system is aligned tension-free. Refer to => [ Exhaust System, Installing ] Exhaust System, Installing.
