Priced at $39.99, the SoundRacer “plugs into your car’s cigarette lighter and uses an FM transmitter to play real V8 or V10 engine sound effects through your vehicle’s stereo.” Video after the break.

The sound changes as you drive and SoundRacer even increases the speed of the engine sound so that you can drive at a normal speed and still get a very exciting engine sound.
