Step 1:( Carefully read all instructions before
installation). To extract your OEM exhaust system it
is required to cut the factory exhaust to remove it. To
do this Measure 3.75" back from the weld on the
pipes behind the catalytic converters and cut. Once
this is done remove the crossmember, unfasten the
hangers from the rubber insulators, Undo the vacuum
line from the muffler and plug. Carefully remove the
complete assembly (retain the rubber insulators as
they will be needed to install your new MAGNAFLOW
system)
Step 2 Before installing your new system the rear
hanger position must be changed. Referencing FIG 1
un-bolt the factory hanger and move it to it's new
position, one place over towards the outside of the
vehicle. install your new exhaust system by first
sliding the inlet pipes of the Resonator Assembly
onto the catalytic converters and locating the
hangers. Slip the Muffler Assembly over the outlets
of the Resonator Assembly and locate the hangers
into the rubber isolators. Use the supplied clamps to
secure.
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.
