20.
If the vehicle is anything other than Standard
Cab 133” wheelbase model, an extension pipe
must be used between the catalytic converter and the
muffler. Vehicle with catalytic converters having a 2 1 ⁄
2
”
converter outlet will require the 2 1 ⁄
2
x 3” adapter and
the extension pipe. Most applications require that the
extension pipe be cut to a specific length. The
following chart lists the extension pipe and adapter
requirements for the various cab/chassis application.
21.
Crew Cab models use an additional hanger to
support the center of the extension pipe. A 3”
clamp/hanger is supplied with the 41” extension pipe.
Install this hanger clamp into the factory rubber hanger
to support the pipe. Do not tighten at this time.
22.
Install Banks Dynaflow muffler onto the catalytic
converter or intermediate pipe. Hang the muffler
by the front and rear hanger clamps in the factory
rubber hangers. leave clamps loose enough for
adjustment.
23.
Install the Monster tailpipe over the axle and into
the muffler outlet and original factory rubber
hanger. Install stainless tip tailpipe and 3 1 ⁄
2
” U-clamp.
24.
Check the alignment of the muffler and tailpipe.
Make sure tailpipe has adequate clearance to all
chassis and suspension components ( 3 ⁄
4
” minimum) to
prevent rattles. When alignment looks good, tighten all
clamps, including flanges at exhaust manifold donut
seal connections.
25.
Remove the plastic silencer from the engine air
inlet hoses between the air cleaner housing and
throttle body. Use a hacksaw to cut 5 ⁄
8
” of hose from the
small end of each of the hoses that went between the
plastic silencer and air cleaner cover. Clean all rubber
chips from inside the hoses after cutting.
26.
Using a hacksaw, remove the tapered portion of
the silencer by sawing as shown in Figure 6 .
Remove any plastic shavings after cuts are completed.
27.
Reinstall the modified silencer in the inlet air
hoses.
For torquetube only installation, proceed to step 30.
28.
Replace the original paper element type air filter
with the low restriction reusable Banks Ram-Air
filter provided. Make sure the filter is seated in the
housing. See the filter service section of these
instructions for filter maintenance and care.
29.
Install new Banks Ram-Air filter cover using four
6mm x 40mm metric hex bolts. Tighten bolts just
enough for cover feet to contact housing base. Do not
overtighten, as this can distort cover and base. Reinstall
hoses and tighten clamps.
NOTE: All 1996 and later California-Only systems (P.N.
48828, 48829, 48838, & 48839) reinstall factory air filter
cover.
30.
Test drive the vehicle. listen for any exhaust
leaks and rattles. Correct leaks and rattles by
tightening or repositioning exhaust piping as required.
NOTE: The exhaust system may smoke somewhat at
first as the grease used in the tube-bending process
burns off the pipes.
