1. Lay out the GIBSON EXHAUST SYSTEM on the floor so it looks like the drawing. Compare manual
part numbers with the part.
2. Remove stock exhaust
from behind the catalytic
converter. For easier removal
cut overaxle just behind the
muffler. Use jack stands to
support the converter. You
will want to keep the
converter supported so it
wont drop.
3. Install headpipe # A. SHORT

pipe # A to length on short bed
models. Use clamp # F to attach
head pipe to factory connector
pipe. Install hanger # I at the rear
of the head pipe using supplied
nuts and bolts. Do not tighten.
4. Slide muffler # B with inside
louvers facing towards the
converter. Use a jack stand to
support the muffler. Install
hanger # G on the muffler outlet.
The long portion of the hanger
will be pointing towards the
driver side. Now, install rear
hanger # H with hanger bolts
facing towards the passenger
side. Install over axle pipe
# C into the outlet of muffler no
less than 1 ½” and no more than
2”. Do not tighten hangers.
5. Slide turn out
pipe # D on the
tailpipe behind the
rear tire. Roll
turnout pipe until
you have it at the
correct angle for
your truck and
clamp # H. Spare
tire may need to be
loosened and
pushed to the rear
to allow for
clearance.
6. Install stainless
steel tip, Clamp down.
