I am eagerly awaiting world that my 2004 Boss (350) is completed. My buddy got his back in January and his pipes have already blued especially around the collector flange. Is this normal due to the high heat the Boss puts out or is there something that needs adjusted fuel mixture wise?

The pipes change their color to blue if you've got too much exhaust flow
resistance, or a too late ignition curve. A little "blueing" is normal at
the collector - but it shouldn't be too much. Mine has a narrow blue ring around the collector, too.
