Warning: 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
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.

Step 1: (Carefully read all instructions before
installation) Begin removal of the OEM exhaust
system by unbolting the inlet flange from the catalytic
converter. Do not damage or discard the OEM clamp
or rubber insulators, as they will be reused to mount
the new system. Disengage the welded hangers from
the OEM rubber insulators and remove the entire
OEM exhaust system.
Step 2: Install the new exhaust system by using a front
to rear method. Attach the inlet pipe assembly using
the OEM fasteners, then insert the welded hangers into
the OEM rubber insulator. Leave all clamps loose for
the final adjustment of the complete system. Using the
supplied 2.50" clamp, install the Resonator Assembly
and the Muffler Assembly in a similiar fashion.
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). Inspect all fasteners after
25-50 miles of operation and retighten if necessary.
