1. Measure 20” across from the inside surface of the passenger side bed rail.

This will be the centerline of the Stack once installed. Ensure that your
measurements are accurate. Mark this location along the bed rail. Refer to
Figure 1.

2. Slide the Band Clamp (from Stack kit – purchased separately) over the

Stack. Wedge the Stack Mounting Bracket between the Band Clamp and
the Stack. Adjust to the bed rail height and tighten the Band Clamp slightly.
Make sure the Stack is vertical and the Stack Mounting Bracket is flush
against the bed rail and centered on the measurement made in Step 1.
Trace a circle around the base of the Stack and center punch the circle’s
center. Verify that the center punch hole is in line with your existing
exhaust and adjust accordingly.

This will be the center line of your Stack.

3. Align the Stack centered on the mark you made in Step 2. Mark the bolt hole

location of the Stack Mounting Bracket onto the front rail of the bed. Center
punch the marks and drill holes to accommodate the 3/8” hardware. Refer
to Figure 2.

4. Loosely attach the Stack Mounting Bracket to the front of the truck bed

using the 3/8” hardware supplied. Set the Stack up in the bed and loosely
attach it to the Stack Mounting Bracket. Make sure the Stack is vertical
and in the desired position. Refer to Figure 3.

5. Confirm 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 Extension Pipe will
pass through the floor. Remove the Stack from the bed of the truck. Drill the
hole using a 5” hole saw. It may be required to cut part of a bed floor rail
away. Refer to Figure 4.
