MagnaFlow BMW 335XI Stainless Cat-Back System PERFORMANCE EXHAUST - Manual

Step 1:(Carefully read all instructions before
installation). To remove the OEM exhaust system
you will need to cut each pipe approximately 5"
rearward of the driver side catalytic converter and 3"
rearward of the passenger side catalytic converter.
Remove the exhaust hangers from the rubber
isolators. Be sure to retain all mounting hardware as
it will be needed to mount your new MAGNAFLOW
performance exhaust system.
Step 2: Begin installing your new exhast system by
slipping the inlet pipes of the X-Pipe assembly over
the outlet pipes you have just cut. Loosely secure
using the supplied clamps. Next slip both inlets of
the Mid pipes over the outlets of the X-Pipe assembly
and loosely secure using the supplied clamps. Mount
the Tail Pipe Muffler assembly by slipping the inlet
pipes over the outlet ends of the Mid pipes. Locate
all hangers to the existing rubber isolators.
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.
