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 31⁄2” 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 31⁄2” clamp onto the front of the supplied rear intermediate pipe.
Note: Review the Parts List Table on page 8 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 31⁄2” clamp onto the front of the intermediate pipe / catalytic converter outlet.
9.Install a 4” clamp onto front the supplied extension pipe. Install the supplied extension pipe onto the outlet of the rear intermediate pipe. Loosely snug the clamp at the connection.
