[EDIT: I guess you already have a way to measure the cat temps]

This may be the thing for you :

High Range Adjustable Temperature Switch with LCD - Jaycar Electronics
Heat can be a major problem with any car, especially modified and performance cars. the more power, the more heat, so you need to ensure you have adequate cooling systems in place. 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 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. Probe does NOT have isolated case. Kit requires probe with insulated case, if mounted to common ground.
The idea would be to install this in your Cat to determine it's warm-up/cool-off time period.
