1.
Raise the vehicle and support it
with properly weight rated safety
stands, ramps, or a commercial hoist.
Follow the manufacturer’s safety
precautions. Take care to balance the
vehicle to prevent it from slipping or
falling. When using ramps, be sure the
front wheels are centered squarely on
the topsides; place the transmission in
park; set the parking brake and place
blocks behind the rear wheels.
CAUTION: Do Not Work Under Any
Vehicle Supported Only By A Jack.
Severe Injury May Result.
WARNING! The following step may
require the use of a torch and/
or saw. Proper safety equipment
should be used. Failure to use
proper safety equipment may
result in severe injury.
2.
Removal of the factory exhaust
can be simplified by cutting the factory
exhaust pipe behind the muffler. This
will allow the tailpipe to be removed
as a separate piece.
3.
Remove the factory tailpipe from
the vehicle by disengaging the exhaust
system hanger pins from the rubber
hangers using a large screw-driver or
pry bar.
Note: Lubricating the rubber hangers
with WD-40 or similar lubricant will
ease removal of the hanger pins.
4.
Remove the factory muffler from
the vehicle by removing the three (3)
nuts from the factory exhaust flange
located at the factory muffler inlet.
5.
Install the Banks flanged
intermediate pipe and 3-bolt gasket
onto the headpipe. Loosely assemble
with the supplied bolts, washers, and
nuts.
6.
Slide the supplied 4” exhaust
hanger clamp onto the outlet of the
Banks flanged intermediate pipe. Insert
the hanger pin into the factory rubber
hanger.
7.
Route the front tailpipe over the
rear axle housing and install onto the
flanged intermediate pipe outlet. Be
sure that the two pipes are completely
engaged. Loosely snug the 4” hanger
clamp.
8.
Install a 4” exhaust clamp onto
the inlet of the rear tailpipe. Install
the rear tailpipe onto the outlet of the
front tailpipe. Insert the rear tailpipe
hanger pin into the factory rubber
hanger. Rotate the tailpipe until the
hanger pins are parallel with the
frame mounted pin. Slide the 4” clamp
and position as shown in Figure 39.
Loosely snug the 4” clamp.
Notes: Maintain an adequate air gap
clearance of one (1) inch between the
exhaust and the shock absorber and
between the exhaust and the spare
tire.
Minimum distance between exhaust
tip and body is one (1) inch.
9.
Adjust each of the pipes to ensure
that all of the hanger pins are parallel
with the frame mounted pins and that
the rubber hangers are all positioned
slightly forward (Figure 40). The
amount of forward angle on the rubber
hangers should increase the farther
downstream the hanger is positioned.
This allows the hangers to be properly
positioned once the exhaust system
reaches operating temperature.
10.
Figure 39 illustrates the proper
location of an exhaust clamp on a
tubing joint. Torque the nuts on each
of the exhaust clamps to 35 ft-lb.
Note: The clamps only need to be tight
enough to form a seal and hold the pipes
together. Over tightening the clamps
may cause the system to leak due to the
pipe being crimped.
