MagnaFlow BMW 325I Stainless Cat-Back System PERFORMANCE EXHAUST - Manual

Step 1: (Carefully read all instructions before
installation). To extract your OEM exhaust system it
is required to cut the factory exhaust to remove it. To
do this Measure 1 3/4" forward of the hanger
mounting bracket as shown in Fig.1 and cut. Once
this is done unfasten the hangers from the rubber
insulators and carefully remove the complete
assembly (retain the rubber insulators as they will be
needed to install your new MAGNAFLOW system)
Step 2 Install your new exhaust system by first
sliding the inlet pipes of the X-Pipe Assembly onto
the catalytic converters and locating the hangers.
Slip the Muffler Assembly over the outlets of the
X-Pipe Assembly and locate the hangers into the
rubber insulators. Use the supplied clamps to secure.
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 65ft-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.
