Installation Instructions #65656B
When installing this exhaust system make sure to use proper safety precautions. Use jack stands when working under the
vehicle, set parking brake, block tires and use safety glasses and gloves. Allow exhaust to cool before attempting
installation. Severe injury or burns could occur if safety measures are not taken.
SUGGESTED TOOLS: 1/2", 9/16", 15mm wrenches & sockets, WD-40, hacksaw, jack stands
1. Disconnect the negative battery cable before removal of OEM exhaust. This will allow the computer to reset and recognize
the new exhaust. Lay out the exhaust on the floor so it looks like the drawing and compare parts with manual.
2. To remove stock exhaust,
unclamp it at the ball flange
behind the Y-pipe. Make sure
to leave all rubber grommets in
the factory location. You will
re-use stock clamp. For
easier removal of exhaust, cut
behind the muffler. Use WD-40
to remove hangers from
grommets.
Next, install headpipe #A into
the factory pipe. Insert welded
hanger into the rubber
grommet. Do not tighten
4. Install muffler #B with inlet
towards Y-pipe. Use jack
stands to support the muffler.
Use clamp #F to secure the
muffler to headpipe. Do not
tighten. Muffler outlets will be
level
5. Make sure muffler outlets
are level before installing
tailpipes. Now install
passenger tailpipe #C. Insert
welded hangers into rubber
grommets.
6. Now install driver side
tailpipe #D. The spare tire may
need to be loosened and
pushed to the driver side to
allow for clearance. Use bolt kit
#H to attach both tailpipes
together.
7. Using clamps #G secure
both tailpipes to the outlets of
the muffler. Rotate tailpipes to
best fit your truck.
8. Install stainless steel tip.
Clamp down. When you have
everything in place, firmly
tighten all bolts and clamps
down securely. Use stainless
steel cleaner weekly to prevent
tip from discoloration. Inspect
all fasteners after 25-50 miles
of operation and re-tighten as
necessary.
GIBSON EXHAUST systems are designed on a factory stock vehicle
Any aftermarket products installed could increase the sound levels of the exhaust.
Make sure there is a 1” clearance from ALL rubber brake lines, shock boots, lines, tires, etc. to prevent
heat related damage or fire.
