Exhaust System, Aligning Free of Stress

Exhaust System, Aligning 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 work procedure must be performed in the specified sequence.
- Dimensions provided in the illustrations are approximate.
- Vehicles without clamp between center and rear muffler

NOTE: Align exhaust system when cold.

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







- Slide exhaust system far enough toward front until end pipe -1- has distance -a- from bumper -2-.
- Dimension a = at least 40 mm
- Tighten screws of front clamp between catalytic converter and main muffler evenly to 40 Nm, installation position







- For correct distance of end pipes/bumper, adjust pre-tension on rear mount for rear muffler to -a-= 7 to 11 mm.
- 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 main 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 clamp between catalytic converter and main muffler evenly to 40 Nm, installation position.







- Slide rear muffler far enough toward front (arrow), until pre-tension at rear right retaining loop on rear muffler a = 7 to 11 mm.
- Tighten screws of rear clamp between main muffler and rear muffler evenly to 40 Nm, installation position.







- Pre-tension of retaining loops is correct when distance -a- is set between end pipes -1- and bumper -2-.
- Dimension a = at least 40 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.
