If you want sound, rather tickle your engine till something like this comes out of it:

Don't think my twingo will sound like that.

We all know that diesels dont have dump valves, as they dont need them ... but for them who feel like there missing out ...

Im not 100% sure on how it gets its air to release, but it works by microswitch much like the "electronic fake" valve, but instead of playing a recorded sound (with could be anything, Ive seen one that plays the sound of a woman having a orgasm!) it does actually release air, therefore giving a more realistic sound .... the fact still stands that its fake though lol
