Buick Riviera 20-70
Wasn't able to floor it until around 20 mph and I mostly eased into the gas as opposed to a full on stomp. Not too bad for a two ton luxury car. All filming was done on a closed track.

Riviera Stock Exhaust
This is the sound of the exhaust on my stock Riviera. Not the best sounding car in the world but I like it.

Riviera 20-60
I floored it after I hit 20. At this point the car was totally stock. I have sinced gutted the airbox which helps it breathe better. You can also hear the supercharger more.
