MagnaFlow FORD MUSTANG Stainless Cat-Back System PERFORMANCE EXHAUST - Manual

Step 1: Begin removing your OEM exhaust system
by first loosening the clamps attaching the x-over
assembly at the outlet of the catalytic converters.
These front clamps will be re-used so it is necessary
to twist the clamps to break the tack weld. Working
front to rear remove the fasteners attaching the side
pipes to the x-over, undo the remaining clamps and
detach all hangers from the rubber insulators. Retain
the insulators, side pipe spacers and gaskets as they
will be used to install your new exhaust system.
Remove the system from the vehicle.
Step 2: Install your new MAGNAFLOW system by
first attaching the X-Pipe Assembly to the catalytic
converter outlets using the OEM clamps, use the
supplied fasteners and OEM retained parts to attach
the side pipes to the X-Pipe Assembly. Next, slip the
Mid-Pipes onto the X-Pipe and secure using the
supplied 3.00" clamps. Finish by installing the Muffler
Assemblies in a similar fashion. Locate all hangers
into the 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). 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.
