All I need to do now is to add a heat shield around the bottom where it begins vertical up to the top of the loader arm where the automotive pipe starts. I was thinking of using something like this and tacking it the the "U" bolt part of the clamps to secure it. I suppose it would be mainly for looks though.
For a heat shield on the exhaust, you might try and find some header wrap at an auto parts store. Might be a little cheaper and easier to install.
