INSTRUCTIONS:
NOTE:  do not tighten any clamps or nuts and bolts until the last step!!  Before cutting any pipes it is a good idea to lay out all the included pipes along side the vehicle and get a good idea of how the pipes will hang on the vehicle.  Please read the instructions fully and thoroughly before you begin.

1)  Remove the exhaust system by cutting the muffler off of the pipe that runs from the muffler to the converter.  You will need to cut the pipe as close to the inlet of the muffler as possible.  If there is an O.E. hanger immediately in front of (less than 2”) the muffler, cut the pipe just in front of this hanger and remove the hanger from the vehicle.

2)  Slide the F4 flange over the male adapter.  Install the 2-1/4” inlet of the male adapter pipe to the existing pipe after the converter, using the 2-1/4” clamp.  

3)  Install the flanged end of the female adapter to the flanged end of the male adapter using the 3/8” x 2-1/2” bolts, nuts, and lock washers.

4)  Install the muffler to the female adapter using a 3” clamp.  The inlet of the muffler is offset, with a center outlet, with the inlet lying away from the drive shaft.

5)  Remove the O.E. hangers that are on the vehicle above the end of where the O.E. muffler was.    Install a THU900 hanger to the frame near where the rear O.E. hanger was.  Use the existing bolt hole if possible, or drill a 5/16” hole in the frame near the O.E. hanger.  Install the hanger using a 5/16” x 1” bolt, nut, fender and lock washer to the frame.  Use the 3” clamp at the connecting point of the muffler and connect the right tail pipe and the hanger assembly.

6)  Install the inlet (long end) of the front tail pipe to the muffler.  Use the clamp from step 5) to connect the two pieces and the hanger.  

7)  Install the rear tail pipe to the front tail pipe using a 3” clamp.  

8)  Where the rear tail pipe crosses under the frame, locate or drill a 5/16” hole in the frame and connect the remaining THU900 hanger to the frame using the 5/16” nut, bolt, lock and fender washer.  Use a 3” clamp to connect the hanger to the rear tail pipe.

9)  Tighten all clamps, nuts, and bolts.  Check for clearance of all brake and fuel lines, and for clearance of all chassis and frame components.
