MagnaFlow FORD DIESEL 6.7L DIESEL, 4in 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
Assy and appropriate clamps. Leave all clamps
loose for final adjustment of the complete system.
Install the Tail Pipe 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.

When working on, under, or around
any vehicle exercise caution. Please allow the
vehicle's exhaust system to cool before removal,
as exhaust system temperatures may cause
severe burns. If working without a lift, always
