Not many made it out the door as I recall. Hadn't heard the super bowl story tho. There was an article a couple years back on VOE. It featured a car with it and described the system. I think it was in one of the Pontiac rags if I recall.
I'm sure Pontiac was responding to the youth when they released VOE (just as Chrysler listened with the release of the budget RR and Superbee 440-6 lift off hoods and no hubcaps). The message: the sound of your car was an important element in your car's reputation. Kids were going to the after market shops big-time to lay down cash for cherry bombs, thrush,. Kudos to Pontiac for taking a shot at their piece of the pie.
