Diffuser project

[The Stickman]

What are you going to do about the areas you cut out on the outsides of the exhaust pipes?

Also if you can bend aluminum, which is not hard to do, you can bond aluminum sheet to rigid foam board which will be light and strong. I think ill be going that route instead of dealing with fiberglass

The outer areas will get smaller tunnels. Problem is the exhaust pipes. The passenger side runs straight down the framerail. But the driver side if off a bit. I think because the fuel tank is offset more towards the driver side the guy doing the exhaust wanted some space between the 2. So I either find a way to get it right under the framerail, or make it exit right after the rear wheels, or do a custom center exhaust exit. But that requires moving the lic plate. And becuase of the window in the tailgate I am not sure If I could event recess the plate. So still working thru ideas.I love to work with aluminum. I never knew about bonding it to foam board. I would love to know more about that.
