Step 1. To begin the removal of the OEM system
you will need to cut 18.25" behind the DPF. You can
then disengage the welded hangers from the rubber
insulators, working rearward finish removing the
system. Do not damage or discard the rubber
insulators, as they will be reused to mount the new
system
.
Step 3. Next Install the Tail Pipe Assembly in a
similar fashion using the supplied 4.00" clamps and
by fitting the welded hangers into the rubber
insulators.
Step 2. Begin installation of the Magnaflow system
by clamping the Inlet Pipe to the newly cut outlet of
the DPF using a supplied 4.00" clamp and fitting the
hangers in the rubber insulators (leave all clamps
loose for final adjustment of the complete system).
Step 4. 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.
