Exhaust System, Installing Free of Stress

Exhaust System, Installing Free Of Stress

To avoid noise and tension in the exhaust system, install exhaust system as follows:

NOTE:
- Requirement for the installation of exhaust system is the exact alignment and tightening of front pipes and catalytic converters.
- Loosen all threaded connections of exhaust system (except exhaust manifold and flange connection, catalytic converter / intermediate pipe).
- Align exhaust system when cold.
- Following procedure must be performed in the specified sequence.
- Dimensions provided in the illustrations are specified dimensions.

Vehicles without clamp between center and rear muffler
- Loosen screws of front clamp between catalytic converter and center muffler.







- Push exhaust system far enough forward (arrow) that the pre-tension at the retaining loop at rear right of rear muffler is a = 9.... 11 mm.
- Tighten screws of front clamps between catalytic converters and center muffler evenly to 40 Nm, installation position.

Vehicles with clamp between center and rear muffler

NOTE: Only for vehicles with double clamp between center and rear mufflers, the center muffler must also be aligned.

- Loosen screws of front clamp between catalytic converter and center muffler.







- Push exhaust system far enough forward (arrow) that the pre-tension at the retaining loop at rear left of front muffler is -a- = 7 - 9 mm.
- Tighten screws of front clamps between catalytic converters and center muffler evenly to 40 Nm, installation position.







- Push rear muffler far enough forward (arrow) that the pre-tension at the retaining loop at rear right of rear muffler is -a- = 9 - 11 mm.
- Tighten screws of rear clamp between main muffler and rear muffler evenly to 40 Nm, installation position.

Tailpipes, aligning







- Align tailpipes so that distance -a- (left side) is equal to distance -a- (right side).
- Dimension -b- between bumper cutout and lower edge of tailpipes must also equal specification.
- Dimension b = 97... 103 mm

Installation position of front double clamp







- Screw tips must not project beyond the lower edge of the clamp.

Installation position of rear double clamp







- Screw tips must not project beyond the lower edge of the clamp.
