MagnaFlow BMW 525I Stainless Cat-Back System PERFORMANCE EXHAUST - Manual

Step 1: (Carefully read all instructions before
installation) Begin removal of the OEM exhaust
system by unfastening the OEM nuts and bolts
located behind the catalytic converter. Do not
damage or discard the rubber insulators or the OEM
fasteners, 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. Using the OEM fasteners install
the resonator assembly by bolting the inlet flanges to
the outlet end of the catalytic converter. Then install
the Muffler Assembly using the supplied 2.50" clamp
and Insert the welded hangers into the OEM rubber
insulator. Leave all clamps loose for the final
adjustment of the complete system.
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.
