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 5” Band 
Clamps over the pieces before they are assembled. Refer to Figure 3. 
 
 
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 3. 
 
 
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 4. 
 
 
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. MBRP Inc. 
recommends using a 6” diameter hole saw. It may be necessary to cut 
part of a bed rail away. Refer to Figure 6. 
 
 
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 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.
