Kind of like when Mythbusters busted the motorcycle vs car pollution test. Things are not always what they seem. One way or the other.
The temp probe I mention in an earlier post can be used to trigger alarms :

... This temperature switch can be set anywhere up to 1200 degrees celsius, so it is extremely versatile. The relay can be used to trigger an extra thermo fan on an intercooler, mount a sensor near your turbo manifold and trigger water spray cooling, or a simple buzzer or light to warn you of a high [or LOW!] temperature. The LCD, which can easily be dash mounted, displays the temperature all the time. kit supplied with a quality solder masked PCB with overlay, LCD panel, temperature probe and all electronic components. ...
In this way the alarm would go off when the temp gets too low. If you could have an alarm for low and *high*, then you could engineer a cat-insulation mechanism that you can also turn on/off while you are driving.
