User 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 11" back from the catalytic converter
weld as shown in Fig.1 and cut both pipes. 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 outlets, (remember to install
the supplied clamps at each junction). Next slip the
Mid-Pipes over the outlets of the X-Pipe Assembly.
Finally slip the Muffler Assemblies over the outlets of
the Mid-pipes and locate the hangers into the rubber
insulators.
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.

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.
