installation instructions
If a heavy duty hoist is available, raise the
vehicle and remove the front wheels for
easier access. If the rear wheels remain on the
ground, block the rear wheels.
Starting from the rear of the vehicle and
working forward, remove the exhaust system
up to and including the front muffler. Leave exhaust
pipe hangers in place on the chassis.
NOTE: Some joints may require the heat from a torch
to loosen them for disassembly.
Install the small, straight-thru primary muffler
to “Y” pipe. Use 3” U-clamp. Install hanger rod
on “Y” pipe into factory hanger.
Install 28” intermediate pipe in outlet
of primary muffler. Install 3” U-clamp to
secure pipe in muffler. Install 3” hanger clamp on
intermediate pipe to support muffler. See Figure 1 .
The Ford Class “A” Motorhome chassis is
supplied in several wheelbase lengths. The
standard length is 178” wheelbase. Longer wheelbase
coaches will require an additional extension pipe.
These are available from Gale Banks Engineering in
a 33” and 53” length to fit 208” and 228” wheelbase
coaches, respectively. Other wheelbase coaches
may be accommodated by cutting one of these two
extension pipes.
Extension pipes are required to fit wheelbase
lengths as follows:
a. 178” wheelbase
no additonal extension pipe required (use 28”
extension pipe supplied in all kits).
B. Up to 208” wheelbase
Requires 33” additional extension pipe.
c. Up to 228” wheelbase
Requires 53” additional extension pipe.
D. Up to 258” wheelbase
Requires 33” and 53” extension pipes.
Install the appropriate additional extension pipe(s) if
required. Wheelbases other than 208 or 228 inches
will require that the extension pipe be shortened.
Add additional 3” hanger clamps (available from Gale
Banks Engineering) as required to support extension
pipes in factory rubber hangers.
Install the secondary muffler on the
intermediate pipe or extension pipe. Support
rear of muffler with muffler hanger U-clamp provided.
See Figure 2 . Do not tighten hanger clamp at this
time. Install, but do not tighten 3” U-clamp at muffler
inlet connection.
Install tailpipe over rear axle and into muffler
outlet connection. Insert tailpipe hanger
pin into factory rubber hanger. Rotate secondary
(rear) muffler as required to best align muffler with
tailpipe and intermediate pipes. Once alignment
is determined, tighten clamps at muffler inlet and
outlet connections. Hanger clamps on intermediate
piping may be loosened and readjusted if necessary.
See Figure 2 .
Install intermediate pipe heat shield on
intermediate pipe between primary and
secondary mufflers. Heat shields install with the
shield above the pipe, to protect the coach floor.
Because the location of factory pipe hangers will
vary, the installer must provide a notch in the heat
shield to clear the hanger rod on the U-clamp hanger.
See Figure 3 . Make two saw cuts through the folded
lip of the heat shield, one inch into the flat section
beyond the fold line. Locate the cuts either side of
the hanger rod location. Fold the metal between
the cuts back against the flat portion of the shield to
provide a clearance notch for the hanger rod. Clamp
the heat shield to the intermediate pipe with two 3”
U-clamps as shown in Figure 3 .
If an extension pipe has been installed
between the intermediate pipe and the
secondary muffler, an additional heat shield will
have been provided with the optional extension
pipe. Overlap this heat shield with the heat shield on
the intermediate pipe as shown in Figure 3 . Mount
the shield so the forward end covers the slip joint
where the extension pipes join. If the extension pipe
had to be shortened for a shorter wheelbase, overlap
the heat shield so that it will cover the slip joints
at each end of the extension pipe. The long heat
shield has clamp holes every few inches to allwo the
shield to be positioned over as much pipe length as
possible when installed. See Figure 3 . Cut notches
as required to clear hanger rods.
Install the chrome tailpipe tip by sliding it over
the end of the tailpipe. If the tailpipe must be
shortened to position the tip near the coach body,
cut the tailpipe to place it 1 to 2 inches within the
outside end of the tailpipe tip. This will minimize
any heat discoloration of the chrome plating on the
tailpipe tip. The chrome tip is provided with a single
3 1 ⁄
2
” U-clamp for mounting.
caution! If tailpipe passes below or within
3 to 4 inches of storage compartments, heat
shielding will be required to eliminate fire danger
or melting of items in the compartments, including
carpet. An optional clamp-on heat shield is available
from Gale Banks Engineering to provide protection
between the tailpipe and compartments above. The
heat shield is supplied with two 3 1 ⁄
2
” U-clamps, use
it and the chrome tip U-clamp for mounting the heat
shield. See Figure 2 .
