Yes, I just finished installing them last weekend and I still have the film in the camera. Haven't had it developed yet. I will post them soon. Here is what I did. I got a used 4" hydraulic cylinder barrell and cut the end off and then cut 1/3 of it off. This gave me 2 pieces of thin wall 4" pipe. One about 16 inches long and the other about 8 inches. I cut and welded them together where the long one had the short one welded on it at an angle. Like a "cutout" that you can by from any parts house. I also fabricated and installed butterflies in both chambers of this cutout and put a linkage that operated both at the same time. When one is opened the other one is closed. This is cable operated from inside the cab. I also removed the cat in the exhaust pipe and installed the test pipe from DC. I cut a section out of this test pipe and installed my homemade cutout. This gives me the option to switch back and forth from the stock muffler and tailpipe to the stacks. From the cutout, on the stack side, I used a piece of 4" flexable exhaust pipe that comes up through the exact center of the bed just behind the front bed support beam. This was a little further back than what I wanted so I took a 4" elbow and cut it in half, rotated one half of it 180 degrees and welded it back together. This gave me a offset that brought the stack assembly forward to the front of the bed. Then I used elbows and stock pieces of 4" exhaust pipe to assemble the "tee" and "90's" until I had the stacks the width and height I wanted. The last thing was a couple of 4" to 5" adapters and then the 5" stacks on top. The tips of the chrome stacks are about 3" above the top of the cab. I like having the option of shutting off the stacks because sometimes I get tired of the noise and like to listen to the radio, and it is safer in town. But when the time and place is right, pulling a load, I like to rattle the windows when I pass by. I really enjoy it. I'll post pictures when I get them developed.
