Exhaust System, Aligning Free of Stress

Align exhaust system to avoid stress in the system and to prevent noise as follows:


NOTE:
- Be sure muffler mountings are free of stress when installing.
- When aligning and relieving stress, loosen all bolted connections (except exhaust manifold), including mountings for catalytic converter.
- Align the exhaust system when cold.
- Perform the work in the order described below.
- Dimensions in the illustrations are approximate.


Vehicles without double clamp between center and rear mufflers


NOTE: The exhaust system must be cold when aligning.


- Loosen double clamp between catalytic converter and center muffler.







- Push exhaust system far enough to the front until the gap (dimension -a-) between tail pipes -1- and rear bumper -2- is achieved:
- Dimension -a- = at least 40 mm (1.5 in.)
- Tighten double clamps between catalytic converters and center mufflers evenly to 40 Nm (30 ft lb). Installation position.







With correct distance between tail pipes/bumper, the rear mount is pre-tensioned to a = 7 to 11 mm (0.3 to .43 in.).

Vehicles with double clamp between center and rear mufflers


NOTE: For vehicles with double clamps between center and rear muffles, the center muffler must also be aligned.


- Loosen bolts of double clamps between catalytic converters and center mufflers.







- Push exhaust pipes forward (in direction of arrow) until pre-tension at left rear mount is at center muffler is a = 7 to 9 mm (0.3 to 0.4 in.).
- Tighten double clamps between catalytic converters and center mufflers evenly to 40 Nm (30 ft lb). Installation position.







- Push rear muffler forward (in direction of arrow) until pre-tension at right rear mount at rear muffler is:
- Dimension a = 7 to 11 mm (0.3 to 0.43 in.)
- Tighten double clamps between and center and rear mufflers evenly to 40 Nm (30 ft lb). Installation position.

Rear mufflers, aligning







With correct pre-tensioning of mountings, the gap between tail pipes -1- and bumper -2- is:
- Dimension -a- = at least 40 mm (1.5 in.)

Double clamps front, installation position







The bolt ends must not protrude beyond lower end of clamp.

Double clamps rear, installation position







The bolt ends must not protrude beyond lower end of clamp.
