Step 1: (Carefully read all instructions before
installation) Removal of the exhaust system on this
vehicle requires cutting and deburring the pipe 3.50"
behind the Pipe/Weld junction at the outlet side of the
secondary catalytic converter (Fig.1). To accomplish
this you must remove the cross brace and Catalytic
Converter shield. After the pipe has been cut, remove
the system by disengaging the welded hangers from
the OEM rubber insulators. Do not damage the
rubber insulators, as they will be used to mount the
new system.

Step 2: Begin installation of the new system by
fastening the Inlet Pipe Assembly to the catalytic
converter extension using the supplied 2.25" clamp,
and by fitting the welded hanger into the OEM rubber
insulator. Leave all clamps and fasteners loose for
final adjustment of the complete system. Install the
remaining assemblies in a similiar fashion using the
supplied band 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 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.

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
consult vehicle manual for correct lifting
specifications. Always wear safety glasses and
ensure a safe work area. Serious injury or death
could occur if safety measures are not followed.
