The America/Speedy headers are double walled, so the outer visible pipe shouldn't show bluing. Next time you look at a standard Bonnie notice the difference in size of the headers compared to your BA's. The Bonnie's head is the same as the BA's, but the headers are smaller OD and not double walled and will blue past the first curve.
Every normal man must be tempted, at times, to spit on his hands, hoist the black flag, and begin slitting throats.
