You can't use a dump valve on a car without a turbo - there's no point.
You can get a kit that has under bonnet speakers to make dump valve noises.
But it sounds so silly when you're going up from 3rd to 4th at 35 mph.
You'll never hear them on a race car as the engine's doing 8000+ RPM when changes are made so it gets obliterated.
Still, if you really want to, why not?
Cheers,
