INSTALLATION INSTRUCTIONS

Step 1. To remove the OEM exhaust system, loosen
the clamp attaching the systems inlet pipes to the
catalytic converter outlet pipes. Disengage all welded
hangers from the OEM rubber insulators. Do not discard
the OEM fasteners or damage the rubber insulators as
they will be needed to mount your new MAGNAFLOW
system.​


Step 2. Before installing your new MAGNAFLOW
system the OEM spare tire and spare tire heat shield
must be permanently removed. Install the new system by
attaching the Inlet Pipe Assembly to the OEM catalytic
converter outlet pipes using the existing clamp and
hardware. Locate the welded hanger to the rubber
insulator. Leave all clamps and fasteners loose for final
adjustment of the complete system once installed.


Step 3. Install the Muffler Assembly to the Inlet Pipe
Assembly using the supplied 3.00" clamp.


Step 4. Install both the Over Axle Pipes using the
supplied 2.50" clamps. Locate the welded hanger to the
OEM rubber insulator.


Step 5. To allow for the installation of a dual outlet
system on a single outlet vehicle you will have top mount
the supplied Hanger Brackets to existing holes in the
factory frame rails using the supplied fasteners (8mm bolt
and panel nut) as shown in the photos. Once completed
you can now slide the Tailpipe assemblies onto the Over
Axle pipes and fasten with the supplied 2.50" clamps and
mount the hangers to the installed hanger brackets using
the supplied rubbber insulators.




Step 6. Once a final position has been chosen for the
new exhaust system, evenly tighten all clamps from front
to rear using the torque specifications on page one of the
instructions. Inspect all fasteners after 25-50 miles of
operation and re-tighten if necessary.
