Exhaust System, Aligning Free of Stress

Exhaust System, Aligning Free of Stress

Align the exhaust system as follows to avoid stresses in the system and prevent the transmission of noise into the body:


NOTE:
- Before assembling the exhaust system, the front exhaust pipes and the catalytic converters must be aligned accurately and secured.
- Loosen all bolted connections on the exhaust system (except exhaust manifold and flange mountings, catalytic converted/intermediate pipe).
- The exhaust system must be aligned when it is cold.
- Keep to the sequence described below.
- The dimensions in the illustrations are approximate.


- Vehicles without clamp between front muffler and rear muffler

- Loosen bolted connections on front clamps between catalytic converters and front muffler.







- Push exhaust system towards front of vehicle -arrow- so that rear mounting of rear muffler is pre-loaded by amount a = 7 ... 9 mm.
- Tighten bolts on front clamps between catalytic converters and front muffler evenly to 40 Nm; installation position.

Aligning tailpipes







- Align tailpipes so that distance -a- is same on both sides.
- At same time, set distance -b- between bumper cut-out and bottom of tailpipes:
- Distance b = 97... 103 mm

- Vehicles with clamp between front muffler and rear muffler


NOTE: It is only necessary to additionally align the front muffler on vehicles with clamp fitted between front muffler and rear muffler.


- Loosen bolted connections on front clamps between catalytic converters and front muffler.
- Loosen bolted connections on rear clamp between front muffler and rear muffler.







- Push exhaust system towards front of vehicle -arrow- so that rear left mounting on front muffler is preloaded by a = 7... 9 mm.
- Tighten bolts on front clamps between catalytic converters and front muffler evenly to 40 Nm; installation position.







- Push rear muffler towards front of vehicle -arrow- so that rear right mounting on rear muffler is preloaded by a = 7 ... 9 mm.
- Tighten bolted connections on rear clamp between front muffler and rear muffler evenly to 40 Nm; installation position.

Aligning tailpipes







- Align tailpipes so that distance -a- is same on both sides.
- At same time, set distance -b- between bumper cut-out and bottom of tailpipes:
