Larry, GP Headers could easily make those pipes for you. I have used them for my Pantera headers. They started out with a set of modified Hall Pantera headers that my friend roughed out. I had them make them up in 304 s/s. I also had them make the exhaust pipes in 304 s/s. The exhaust pipes are 3” in diameter. They will make them up in any material that you choose. Hope this helps.
