attenuate exhaust noise. Second it provides an exit path for the exhaust
from the vehicle. It also is designed to help control the temperature of
the exhaust during DPF regeneration events. The visible holes in each
leg of the twin tip and the holes under the shield just inboard of the
right rear tire(s) are functional. The holes need to be kept clear of
mud/debris or foreign material to maintain proper function of the
exhaust system. Clean and remove debris or foreign material if present
as needed. Spraying with a hose during regular washing of vehicle should
help keep holes clean and clear of debris or foreign material.
Note:
Additions of aftermarket devices or modifications to the exhaust
system can reduce the effectiveness of the exhaust system as well as
cause damage to the exhaust system and/or engine. These actions may
also affect the vehicle’s warranty. See the
Customer Information Guide
for more information.
WARNING:
Failure to maintain the functional holes, in the
tailpipe section of the exhaust, clean and free of debris or
foreign material may result in the holes becoming blocked or plugged.
Do not modify or remove the tail-pipe section. Blocked or plugged
holes or removal/modification of the system could result in elevated
exhaust gas temperatures which may result in vehicle/property damage
or personal injury.
WARNING:
The normal operating temperature of the exhaust
system is very high. Never work around or attempt to repair any
part of the exhaust system until it has cooled. Use special care when
working around the diesel oxidation catalytic converter and/or the
diesel particulate filter (DPF). The diesel oxidation catalytic converter
and/or the DPF heats up to a high temperature after only a short
period of engine operation and can stay hot even after the engine is
turned off. Failure to follow these instructions may result in personal
injury.
