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
Assembly is level.
7. 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 14” Elbow to pass by any frame cross members. Remove
or modify any heat shields that may cause interference.
8. Cut a hole through the truck bed providing adequate clearance
around the part of the T-Pipe that passes through the truck bed.
MBRP Inc. recommends using a 6” diameter hole saw. It may be
required to cut away part of a bed rail. Refer to Figure 6.
9. 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 Assembly at the desired height, loosely attach
the Stacks to the Mounting Brackets making sure that they are
straight. This will hold the assembly steady while you line up to
the exhaust under the vehicle. Refer to Figure 7.
10. Measure from the T-Pipe slip joint to the Extension Pipe. Mark
and cut the shorter side of the 14” Elbow to the required length
so that it lines up with the front part of the exhaust system. Refer
to Figure 8.
11. Attach the 14” Elbow to the T-Pipe slip joint and then attach the
Flex Pipe to both the 14” Elbow and the Extension Pipe. Be
sure to slide the required Clamps over the 14” Elbow and Flex
Pipe before connecting it then to the Extension Pipe. Refer to
Figure 9.
12. Make sure that the Mounting Brackets are centered on the
Stacks and tighten the fasteners holding the Mounting
Brackets to the front of the truck bed. Tighten all Clamps
making sure that the Stacks remain properly aligned.
