But those engine sounds are only hearable inside the car, right? You'd still have to set up some kind of speaker/amp solution to pipe the sounds outside? Something that would stop when you start to load your Kenny G playlist.A popular solution: The V Twin Motorcycle seems most appropriate.
BTW, I've seen the videos of the tests of the new Elio engine. It sounds hella powerful, but has anyone gotten any recordings of how the Elio sounds to bystanders?
