MagnaFlow NISSAN GT-R Stainless Cat-Back System PERFORMANCE EXHAUST - Manual

Step 1: This Magnaflow system re-uses the
factory tips for best aesthetics, remember to
remove them for installation later. Begin
removing your OEM exhaust system by
un-fastening the two bolt flange at the outlet of
the catalytic converters. Working front to rear
detach all hangers from the rubber isolators.
Remove the system from the vehicle. To
facilitate easier installation, at this point un-bolt
and remove the two rear muffler hanger
assemblies from the vehicle.
Step 2: Install your new MAGNAFLOW system
by first attaching the Inlet Pipe Assembly to the
catalytic converter outlet flange. Locate the
hanger to the rubber isolator. At this point (ON
THE GROUND) begin assembling the
remainder of the system. Loosely assemble the
T-Pipe and both Muffler Assemblies with the
supplied clamps and fasteners (Fig 1.), at this
point also mount the rear hanger assemblies
(that were removed previous) to the Muffler
Assemblies. Install this complete assembly as
one piece by inserting the T-Pipe inlet into the
Inlet Pipe Assembly, inserting the hangers into
rubber isolators and bolting the muffler hanger
assemblies to the car.
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.) At
this point re-install the factory tips and center in
the fascia opening.
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.
