Old Dune Buggy Engine sound?

[FaultySanity]

Is there a way i can rip the old dune buggy sound from the old HL2 demos - and replace it with the one in game? I think it sounds so much cooler and i'd kill to have it in-game.

So, any help on where programs i would need to use or even if its possible...tha'd be great! :thumbs:
