Step 1. To remove the OEM exhaust system, you
will first need to cut the pipe behind the muffler
before it goes over the axle. You can then
disengage the welded hangers from the rubber
insulators and remove the tailpipe. Unfasten the
muffler inlet from the catalytic converter at the clamp
junction. Do not damage or discard the OEM
fasteners or rubber insulators, as they will be reused
to mount the new system. Disengage the muffler
hangers and remove it from the vehicle
.
Step 2. Before installing your new system, to
convert the vehicle to dual tips you must install the
supplied threaded hanger into the driver side frame
rail with the supplied fasteners as shown.
Step 3. Install the new Inlet Pipe Assembly at the
ball flare using the OEM clamp. Leave all clamps
and fasteners loose for final adjustment of the
complete system.
Step 4. Working front to rear install the remaining
pieces of the MAGNAFLOW system, inserting
hangers into rubber insulators and loosley intstalling
suppled clamps. Adjustable tips are supplied to fit a
variety of aftermarket bumpers and rollpans, once a
position is decided for the tips it is recommended to
have them welded into place.
