Installation

:

 

 

1)

 

On the inside of the rear frame rails, roughly 10” forward of the bumper, you will find holes that will be 
used to mount the tailpipe hanger brackets. You should see a square hole with a round hole just below it.  
Carefully place the 3/8” bolts through the square hole and back so that they stick out of the round hole. 
Then place the hanger brackets 

#310HA

(left) and 

#311HA

(right) onto the bolts, and secure with nuts 

and lock washers.  Slide a rubber hanger 

#HA168

 onto each of the hanger mounts. 

 

2)

 

On the right, rear section of the floor pan just ahead of the rear axle there is a factory hanger bracket spot 
welded in place. Fasten the hanger mount 

#309HA

 to the inner side of the bracket with a 3/8” bolt 

washer and nut.  Slide a rubber hanger 

#HA168

 onto the hanger mount.  Slide clamp hanger 

#287HA

 

into bottom hole of the rubber hanger. The hanger rod should be inserted from the inside, out

.  

 

 

3)

 

For the left side there are no factory locations for a hanger, so you will need to drill some holes.  Take 
the hanger mount 

#308HA

 and try to mirror the location of the right hanger as close as you can.  Mark 

the two hole locations and drill the pan with a 3/8” bit.  Now you must go inside the vehicle and remove 
the rear seat so that you can see the holes you drilled.  Place the mounting plate 

#244HA

 through the 

holes, and replace the seat. Now go back and fasten the hanger mount in place with 3/8” nuts and 
washers.  Slide a rubber hanger 

#HA168

 onto the hanger mount.  Slide clamp hanger 

#288HA

 into 

bottom hole of the rubber hanger. The hanger rod should be inserted from the inside, out

.  

 

 

4)

 

Place the mufflers up into position and support with stands, then place the outlets of the mufflers into the 
clamp hangers and tighten just enough to hold in place.  

 

5)

 Slide a 

3” clamp #MC300R

 over each muffler inlet, then place H-pipe assembly 

#26168

 in its 

approximate position underneath the vehicle and connect the back of H-Pipes into the muffler inlets and 
support with a stand. Tighten clamps just enough to hold but loose enough to allow for adjustment. 

 

6)

 

Place both tailpipes 

#26170 and #26171

 up over the rear axle, and into the outlets of the mufflers. Slip 

the hanger rods at the rear of the pipes into the rubber hangers that were installed in step 1. 

 

7)

 

The front connector pipes 

#26172 and #26173

 are long enough to allow for many different header 

combinations therefore, it is necessary to determine the proper length of the connector pipes. Once the 
proper length is determined, trim the front connector pipes to fit.
