Installing Exhaust Components
Important:
| • | Ensure that any exhaust system parts that you replace meet the
original equipment manufacturer (OEM) standard. This action will ensure that
the vehicle operates as designed. |
| • | When you replace the muffler, you should also replace the tail
pipe. |
| • | When you install the exhaust pipe to the engine manifold, use
new packings and new nuts. Clean the engine manifold stud threads with a wire
brush before installing the new nuts. |
When aligning the system, leave all of the bolts and the nuts loose
until all of the components are properly aligned. Then tighten the bolts
and the nuts, working from the front to the rear.
If any of the following components are damaged, replace the components.
This action will maintain the correct exhaust system alignment.
