Installation Instructions #5403
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, and 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 the stock
exhaust, unbolt it at the 2-bolt
flange located in front of the
muffler. Disengage the welded
hangers using WD-40 from the
OEM rubber grommets. Do
not damage stock nuts and
bolts or remove the rubber
grommets as you will re-use
them to mount your new
system. Now, cut off tailpipe
and remove exhaust.
3. Install headpipe #A onto
your existing stock flange and
attach using stock hardware.
Do not tighten. Insert welded
hanger into rubber grommet.
4. Install muffler #B onto
headpipe 1.5-2” with the
louvers facing towards the
converter. Use a jack stand to
support the muffler. Use clamp
#G to secure the muffler to
the headpipe. Do not tighten.
Muffler inlet is looking into
louvers.
5. Next, remove your spare tire
and spare tire heat shield. Kit
will only fit with those items
removed.
6. Install passenger side
tailpipe #C into muffler 1.5-2”.
Use clamp #H to secure pipes
together. Do not tighten.
Insert welded hanger into
rubber grommet.
6. Install tailpipe #D into

7. Install rear tailpipe hanger
#I. Remove hitch bolt as seen

grommet on hanger.
8. Install exit pipe #E onto the
tailpipe 1.5-2” and secure with
clamp #H. Do not tighten.
Rotate pipe to best suit your
vehicle. Insert welded hanger
into rubber grommet. Adjust
pipes to fit your vehicle with
tips on so you make sure there
is proper clearance.
9. Install stainless steel tip.
Clamp down. When you have
everything in place, firmly
tighten all bolts and clamps
down securely. Use stainless
steel or aluminum cleaner 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.
