rotate the muffler as required to best align
the muffler/tailpipe assembly. if extension pipes
are used between the muffler and the catalytic
converter, make sure that the overall length of the
tailpipe/muffler/extension pipe combination allows
the rubber tailpipe hangers to hang approximately
straight down. if the hangers angle back, it may
place the tailpipe outlet too close to the tire for
adequate clearance, especially if the optional
chrome tip or heat shield is to be installed.
because of variations in vehicle wheelbases,
it may be necessary to shorten the extension
pipe to provide adequate clearance between the
tailpipe outlet and the tire. when correct, tighten
all u-clamps.
10.
an additional hanger is required to support
the outboard end of the tailpipe. this hanger
hooks under a heavy wire strap that spans a
3 1 /
2
” u-clamp. see figure 1. if the optional
chrome tailpipe heat shield is to be installed (see
subsequent steps), it should be mocked up as the
hanger will tie into one of their mounting clamps.
warning! if the tailpipe end passes under or near
a built-in storage compartment, hoses, wiring,
plumbing, or other items that may be affected by
high temperature, we strongly recommend that
an optional exhaust heat shield, available from
banks, be utilized if any of these items are less
than 4” from the underside of the body as it exits
the vehicle, a heat shield is also recommended to
protect the body.
11.
Determine a method for attaching the
rearmost tailpipe hanger to the coach body
or chassis structure. because there are many
different coach configurations, the installer will
have to select a method of attachment. make sure
that the supporting area is substantial enough to
handle the weight and vibration of the tailpipe
assembly. an extension for the hanger is provided
along with three 5 /
16
–18 x 1” hex bolts and 5 /
16
–18
locknuts.
12.
install the tailpipe tip and optional heat shield
assembly. see figure 1. note that one of the 3 1 /
2
”
u-clamps is used to secure the rearmost hanger
for the tailpipe.

1988-91 models only: remove plastic
air intake silencer from air inlet hoses between air
filter assembly and engine. using a hacksaw, cut
the tapered sections off the silencer as shown in
figure 2. reinstall the silencer in the air intake
hoses using the original clamps. this increases air
flow through the intake system.
14.
remove the air cleaner housing cover.
replace the factory paper element with the
low-restriction banks ram-air™ filter element
provided.
15.
on 1992 and later Vehicles: replace
the factory plastic air inlet duct with the banks
ram-air super-scoop™, provided. transfer the
plastic fitting and clip from the old duct to the
new super-scoop.
16.
start engine and listen for any exhaust
leaks. tighten bolts or clamps to correct leaks as
required. allow engine to warm up and test drive
vehicle.
NOTE: Exhaust tubing will smoke for the first
15-20 minutes of operation. This is normal, as
grease used in the bending process will burn off
the inside of the pipes.
17.
three banks powerpack plaques have
been included in your kit. these may be affixed
to your vehicle by pealing off the backing and
pressing firmly in the desired location. a piece of
masking tap applied to the vehicle with reference
measurements to other emblems or body trim
may be used to level and locate your plaques.
figure 3 shows suggested locations for plaques.
