Removal of Stock System:

Apply a penetrating lubricant liberally to all exhaust fasteners, hangers

and rubber insulators.

Loosen the nut on the band clamp located behind the Diesel

Particulate Filter (DPF).

Remove the muffler and tail pipe from the OEM rubber hangers. If a

hoist is being used the system can be removed in one piece by
removing the passenger side bottom shock bolt and swinging the
shock out of the way. Separate the stock exhaust system at the slip
joint located behind the DPF. Remove the muffler and tail pipe from
under the truck. Be sure to re-install the bottom shock bolt. If a
hoist is not being used you will have to cut the tail pipe at the over axle
section, behind the muffler and remove the exhaust in two pieces.
Refer to Figure 1.

””””

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

Mark this location along the bed rail. This will be the approximate centerline
of the Stack once installed. Refer to Figure 2.

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

Stack. Wedge the Stack Mounting Bracket between the Band Clamp and
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.
Refer to Figure 3.

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 3.

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

using a 3/8” Bolt (included with the Stack Mounting Bracket). 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.
