Wondering if anyone has pics of single stacks installed and how you mounted them to the bed and etc. ?? :D

I ran a single stack setup on my LBZ and have some pics in my garage. I'm working on a similar setup for my LMM, pics of which will be in my garage in the next few weeks I hope. I'm not sure if I'm answering more than what you asked, or how much you already know about DIY stack setups, so I guess this falls under the "etc" category. :D

For a single offset setup, you just need to connect a piece of flex pipe (approximately 12" is what I used; this allows movement and reduces strain on your turbo flange) to your current setup, followed by a 90 degree elbow, which will protrude through a hole in the bed. Then using the necessary reducers (depending on your current exhaust and stack size), attach your stack. 36" should get you to the top of the cab. As far as mounting your stack to the bed, I found a chrome tabbed bracket at a local truck stop that mounted on top of the front rail and worked well. The top of my stack was just above cab height, the theory being that this would reduce drone. Also, a quarter inch hole was drilled at the transition point in the 90 degree elbow, to drain any water that was accumulated after a rain. Like I said, I should have pics up soon and let me know if you'd like any specific ones. Good luck
