5. Confirm that the base of the Stack is resting in the same position as in Step
2. Re-trace and center punch if needed. This is where the 18” Extension
Pipe will pass through the floor. Remove the Stack from the bed of the
truck. Drill the hole using a 5” saw. It may be required to cut part of a bed
floor rail away. Refer to Figure 5 & 6.
6. Install the 3.5”- 4” Adapter with a 3.5” Clamp over the outlet of the DPF.
Pay attention to the alignment notch in the 3.5”- 4” Adapter and the pin
located on the outlet of the DPF. Ensure that the Adapter is fully seated.
Refer to Figure 7.
7. Install the Flex Pipe onto the outlet of the 3.5”- 4” Adapter. Place the 20”
Elbow in position and mark the locations to cut. Allow 3” of overlap at the
Flex Pipe and Elbow connections. Cut the Elbow to the required length and
install. Remember to slide the required Clamps onto the parts before
assembly. Refer to Figure 8.
8. Slide the Bed Mounting Bracket onto the Extension Pipe. Install the
assembly on the outlet of the Elbow with the required Clamp. Reinstall the
Stack by sliding the inlet over the Extension Pipe then securing the Stack
to the Mounting Bracket with the Clamp supplied with your Stack. Align the
system and tighten all Clamps to ensure your
“Smokers “Smokers “Smokers “Smokers
TM TM TM TM
”””” exhaust system
remains properly aligned.
9. Slide the Bed Mounting Bracket to the desired position on the Extension
Pipe to allow installation of the mounting hardware. Ensure the Stack is
vertical. Trace the Bed Mounting Bracket hole from the bracket to the floor
and drill a hole to accommodate the 3/8” hardware supplied. Secure the
Bed Mounting Bracket to the truck and tighten the Clamp to the Extension
Pipe. The Bed Mounting Bracket will ensure the Stack remains in position
and doesn’t vibrate.
10. Check along the whole length of the exhaust to ensure that there is
adequate clearance around fuel lines, brake lines and any wiring. If any
interference is detected relocate or adjust.
