exhaust stack info needed

[warhammercustoms]

I am looking into building a truck with a 7.3 powerstroke in it and would like to use stacks on it. I think it would look cool with the stacks poking out of the top of the shell. I need to know how hot those bed mounted stacks get.
Any body able to help me out?

Here is a pic of the truck it's going in...the stacks will come up in the bed then through the topper in the front. I need to know how much heat is generated and if it would be possible to shield them or compartment off the front of the bed,(area where the stacks pass through) to control the heat.

That will look cool. Let us know what you come up with

it does not melt my plastic bed liner at the hottest point. At the top where they would go through i would not see heat being a problem

How close does it come to the bed liner?

i used to have mine pretty much sitting on the liner and it never melted it

What about air temp inside the camper shell part? would a tube over the stack with a 1 inch air gap between be enough to keep the outer tube cool enough to touch?

my stacks sit right on my bed liner, no problems. If i were going to be doing something fancy like that i would probably buy the diamond plate cover shield some guys make. Im sure they would be cool to the touch.

I had a milk crate in the bed and it slid forward and was leaning against the stack, and it melted the milk crate FWIW.
