Yea, I've definitely thought about doing it. With the bed off the truck right now it's given me an opportunity to poke around back there and I see some things I want to address. As a side note, the vent line, imo, needs to sit up higher and the hose has way too much of a bend in it, so much that it even dips below the level of the top of the tank. To me, I feel like that leaves the chance for fuel to get in there and block the vent line from doing an efficient job.
Beyond that and with the truck running, I really don't feel a lot of radiant heat coming off the pipes. I (reluctantly, and carefully) felt close to the pipes near the tank and fuel lines and do not think it is nearly as bad as I had expected. But common sense tells me I should prevent as much heat as possible from attacking the fuel lines. This is especially bad up front in the engine bay and where the fuel line runs along the frame rail to the pump.
In the back though, I was thinking about maybe sticking on some of that heat reflective adhesive on the sides of the tank closest to the pipes. Like this...

So where does that leave me. Well, this is exhaust is in one piece. I appreciate that it doesn't leave any room for an exhaust leak, but if I knew how to weld, I would honestly cut it right by the muffler and have the pieces ceramic coated. I would prefer that over wrapping the pipe. A lot of varying opinions on heat wrap and every time I go to pull the trigger on some wrap, I read something that convinces me otherwise, or someone talks me out of it.
Am I over-analyzing this? Or do you guys think I should put something on the pipes and ceramic coat the stock cast manifolds to keep heat to a minimum?
