4. 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 clamps over the pieces before
they are assembled. Refer to Figure 5.
5. Place the Stacks onto the T-Pipe assembly and place into 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. Refer to Figure 5.
6. 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 a Mounting Bracket onto each Stack 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. Refer to Figure 6.
7. 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 assembly is level.
8. Mark the bed floor where the T-Pipe is resting. MBRP Inc. recommends
tracing around where the T-Pipe meets the bed floor. Refer to Figure 5. Remove
Stacks and T-Pipe Assembly from the bed of the truck. Find the center of the
circle traced onto the bed floor, mark and center punch it. Go under the vehicle
and locate the center punch mark. This marks the location where you are going
to cut a hole for the T-Pipe to pass through the bed of the truck. If you cannot
find the center punch mark use a small drill to create a pilot hole. Make sure that
there is clearance for the 20”x 14” Elbow to pass by any frame cross members.
Remove or modify any heat shields that may cause interference.
9. Cut a hole through the truck bed providing adequate clearance around the part
of the “T” Pipe that passes through the truck bed. MBRPinc. recommends using
a 6” diameter hole saw. It may be necessary to cut part of a bed rail away.
Refer to Figure 8.
10. Set the “T” Pipe assembly at the desired height from the floor of the bed
(This will set the height of the Stacks). Using spacers to hold the “T” Pipe at
the desired height, loosely attaching the Stacks to the Mounting Brackets
making sure that they are straight. This will hold the assembly steady while you
line the system up to the exhaust under the vehicle. Refer to Figure 9.
