If necessary, correct dimension x as follows
Scheme 514
- Loosen nuts - arrows - of brace between exhaust pipes.
- Adjust distance between rear mufflers.
- Tighten nut to 25 Nm.
Scheme 515
- 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 exhaust system is aligned tension-free --> «Exhaust system, installing free of tension»(/audi/s4/b7-2004-2008/remont/cooling-fan/#42l-v8-5v-engine-mechanical-engine-codes-bhf__exhaust-system-installing-free-of-tension) .
