MagnaFlow LINCOLN TRUCK MARK LT Stainless Cat-Back System PERFORMANCE EXHAUST - Manual

Step 1: (Carefully read all instructions before
installation) Unbolt the clamp attaching the OEM
muffler inlet to the catalytic converter extension. The
OEM system can now be removed by disengaging
the welded hangers from the OEM rubber isolators
(Do not damage the OEM rubber isolators, as they
will be reused to mount the new system.) You may
need to cut the tailpipe about 1" behind the muffler to
aid in removal.
Step 2: Early 2004 trucks will need to use the 24"
long intermediate pipe, and newer models will use the
18" intermediate pipe. Once you've determined which
length you need, fasten the inlet-end to the catalytic
converter extension using the OEM clamp assembly
and by fitting the welded hanger into the OEM rubber
insulator, if applicable (Leave all clamps and
fasteners loose for final adjustment of the complete
system.) Install the extension pipe, muffler sub
assembly, and tip in the same fashion using the
supplied clamps.
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 65ft-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.
