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 exhaust system by
slipping the inlets of the X-Pipe Assembly over the
recently cut outlet pipes and loosely secure using the
supplied clamps. Fit the remaining pieces in a similar
fashion using the supplied hardware and OEM
isolators. 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 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.
