the Banks exhaust system. Be careful
not to trim an excessive amount of
tubing.
Be sure to wear proper
safety equipment.
IMPORTANT: Diesel catalysts may
become plugged with soot which
can restrict exhaust flow, impeding
performance. Inspect the converter
by shining a powerful flashlight into
the inlet. Observe the light through
the other end of the converter.
The full circle of the flashlight should
be visible without any blockage
in the gridwork of the catalyst.
If excessive soot is observed, the
catalyst may need to be cleaned.
TAKE PRECAUTIONS to avoid blowing
soot toward the work area or where
it could be inhaled. ALWAYS use
breathing protection. Also inspect
the catalyst for damage (i.e. chips,
bent corners, etc.) to the gridwork.
If your catalytic converter is
damaged, it may be covered under
your vehicle’s emissions warranty.
A) With the catalytic converter
removed from the vehicle and the
headpipe removed from the converter,
measure approximately 4" from the
weld and mark the location (this
location should be before any bend,
about 7" rear of the inlet flange). Using
a reciprocating saw or equivalent,
vertically cut and remove 7" from the
converter outlet tubing (see
Figure 2).
B) Install the supplied Banks front
intermediate pipe onto the previously
installed Banks T.O.P. Loosely install
a supplied 4" exhaust clamp onto
the forward end of the front
intermediate pipe.
C) Install the supplied 3
1
⁄2" clamp onto
the outlet of the front intermediate pipe.
Place the trimmed catalytic converter
onto the previously installed front
intermediate pipe. Loosely snug the
clamp onto the catalytic converter inlet.
7. Place a supplied 3
1
⁄2" clamp
onto the front of the supplied rear
intermediate pipe.
Note: Review the Parts List Table on
page 11 to verify the rear intermediate
pipe P/N.
8. Install the supplied rear intermediate
pipe onto the catalytic converter outlet.
Be sure the notch and catalytic converter
pin are properly aligned. Lightly snug
the 3
1
⁄2" clamp onto the front of the
intermediate pipe / catalytic converter
outlet. For
crew-cab long-bed models,
install the supplied extension pipe onto
