MagnaFlow SUBARU IMPREZA WRX Stainless Cat-Back System PERFORMANCE EXHAUST - Manual

Step 1:(Carefully read all instructions before
installation) Begin the removal process of your OEM
system by first unbolting the inlet flange from the
catalytic converter. Working front to rear unbolt the
system and remove all welded hangers from the
rubber isolators. The OEM exhaust can now be
removed. During the removal process be sure not to
damage the mounting hardware as it will be needed
to mount your new MAGNAFLOW system.
Step 2: Install your new exhaust system by first
bolting the flange of the Inlet Pipe Assembly to the
outlet of the catalytic converter using the OEM
hardware. Slip the inlet of the Y-pipe Assembly over
the outlet of the inlet pipe assembly using the
supplied 3.0" clamp, locating the welded hanger to
the rubber isolator. Mount both Muffler Assemblies in
the same fashion using the supplied 3.0" 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.

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.
