My exhaust manifold/turbocharger housing glows red at night! Is there a fix?

No, this is normal. Exhaust gas temperatures on DSMs range from about 775 degC to 825 degC on-highway, depending on whether you are within or over the speed limit. Most materials start to get 'red' hot at about 800 degrees C. The only solution to this 'problem' is to take it easy on the throttle.
