Has anyone here pieced together and installed their own dual stack kit? I can probably get everything I would need out of our Nelson catalog at work at cost, so I'm thinking it should be cheaper than buying a kit from some where. Also, I'd like to do something a little different and bring my stacks up on either side of my third brake light instead of the outer corners of the bed. I've seen a few trucks like this in the magazines and really like it, but I've never seen a pic of the in bed tubing to see how they do it. Do I need to fab a box up to mount the stacks in, or do you think I could do with with a "y" pipe coming up thru the bed for the pass. side stack and a 90* elbow coming out of that for the driver side? I'm not sure if the elbow will come up to the same height as the y pipe. I'd like to go with 5" tubing and 6" mitre cut stacks. Thanks for any help or suggestions.
