Of course, the smog police would have to know what the maximum hp, at what rpm, of every car made or sold in the golden state. That's quite a data base.

My guess, is you're correct Don. They just rev up the car until the meter register's 96db, and then issue a fix it ticket. I assume that if the violater doesn't fix the car, then it goes on his or her record as a "mover". But I may be wrong.
