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
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.

Resonator/Tailpipe assembly maintenance
The diesel resonator tail-pipe assembly is a uniquely functioning device
that accompanies the Oxidation Catalyst/DPF assembly. The assembly
serves multiple functions. First it serves as an acoustic device to
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/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 vehicle’s warranty guide for
more information.
