1. Install the Down Pipe in the same position as the stock down pipe placing
the hanger into the OEM rubber insulator and attaching the flared end to the
turbo using the supplied hardware. Do not fully tighten until all components
are in place. See Figure 1.
2. Loosely install the Extension Pipe over the Down Pipe. The Extension
Pipe may require cutting to accommodate vehicles other than the Quad Cab
Long Bed.
3. Loosely assemble the in bed portion of the “T” Pipe assembly. Some
models may require trimming of the “T” Pipe in order to accommodate the
width of the truck bed and the Stacks. Be sure to place the Band Clamps over
the pieces before they are assembled.
4. Place the Stacks onto the 13” and 37” Elbows assembled to the “T” Pipe
Assembly and place in the desired position in the truck bed. The 37” Elbow
should be on the driver side so that the “T” Pipe passes through the bed floor
on the passenger side. See Figure 2.
5. Place the Mounting Brackets between the Stacks and the front of the truck
bed so that the Stacks are properly spaced from the front of the truck bed.
Center the Mounting Brackets on the Stacks and mark the front of the truck
bed in the center of the slotted holes in the Mounting Brackets. Center punch
the marks and drill holes to accommodate a 3/8” Bolt. See Figure 3.
6. Loosely attach the Mounting Brackets to the front of the truck bed using
the 3/8” hardware supplied. Set the Stacks up in the bed and loosely attach
them to the Mounting Brackets. Make sure the Stacks are in the desired
position and the “T” Pipe assembled with the 13” and 37” Elbows is level.
