6. Place the Stacks onto the 13” and 37” Elbows assembled to the “T” Pipe 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 3.
7. 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 the 3/8” Bolts included with the Mounting Kit.
See Figure 4.
8. 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.
9. Mark the bed floor where the “T” Pipe is resting. MBRP Inc. recommends
tracing around where the “T” Pipe meets the bed floor. See Figure 5. Remove
the 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 drill a small pilot hole. Make sure that there is
clearance for the 20” Elbow to pass by any frame cross members.
10 . 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 part of a bed rail away.
See Figure 6.
11. Set the “T” Pipe, assembled with the 13” and 37” Elbows 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 and both 13” and 37” Elbows 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 the system up to the
exhaust under the vehicle. See Figure 7.
