MagnaFlow FORD DIESEL 6.7L DIESEL, 4in DUAL Aluminized Pro Series Diesel PERFORMANCE EXHAUST - Manual

Step 1: First un-bolt the OEM exhaust from the
catalytic converter at the 3 bolt flange. You can
now disengage the welded hangers from the
rubber insulators and remove the exhaust
system from the vehicle. Do not damage the
OEM rubber insulators, as they will be reused to
mount the new system. You may also cut the
tailpipe behind the muffler to aid in removal of
the system.
Step 2: Install the flanged inlet pipe to the
catalytic converter outlet. Crew Cab and Long
Bed (CC/LB) models require the 19" Extension
Pipe, shorter vehicles will now use the Mid-Pipe
Assembly and appropriate clamps. Leave all
clamps loose for final adjustment of the
complete system. Tailpipe Assembly in a similar
fashion using the supplied 4.00" clamp and by
fitting the welded hangers into the rubber
insulators.
Step 3: With all components mounted loosely,
adjust the system for overall aesthetics and
clearance of frame & bodywork. (MAGNAFLOW
recommends at least 1/2" of clearance between
the exhaust system and any body panels to
prevent heat-related body damage or fire.)
Step 4: Once a final position has been chosen
for the new system, evenly tighten all fasteners
from front to rear. The supplied band clamps
must be VERY tight to properly align the pipes
and prevent leaks (Approximately 40ft-lbs).
U-bolt clamps should be tightened to
approximately 30-35ft-lbs. Inspect all fasteners
after 25-50 miles of operation and retighten if
necessary.
