Step 1:( Carefully read all instructions before
installation). To extract your OEM exhaust system,
begin by removing the cross member and loosening
the OEM clamps behind the catalytic converters.
Working front to rear, remove the hangers from the
rubber isolators and remove the system. Make sure
to retain all hardware as it will be needed to install
your new MAGNAFLOW performance exhaust
system.
Step 2: Install your new exhaust system by sliding
the inlet pipes of the X-Pipe Assembly into the
clamps on the catalytic converters and locating the
hangers. Slip the Muffler Assemblies over the outlets
of the X-pipe 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 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.
