MagnaFlow BMW 528I Stainless Cat-Back System PERFORMANCE EXHAUST - Manual

Step 1: (Carefully read all instructions before
installation) Begin removal of the OEM exhaust
system by loosening the OEM clamps located behind
the catalytic converter. Do not damage or discard the
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. Using the supplied 2.25" clamp,
install the resonator assembly. Then install the
Muffler Assembly in a similiar fashion 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.
