Well, it’s pretty shrill…and funny. It sounds like, well, a bunch of party horns going off at once. If you watch this without busting a gut, there’s something wrong with you. It’s going to be the funniest 15 seconds of your life…guaranteed (or you get something back). https://www.youtube.com/watch?v=iELnlCZPR5Y
I’m very tempted to do this to my car, as it has dual exhaust pipes. Yup, that means I’ll have 100 party horns. Maybe somebody with a Top Fuel dragster will do this, but they’ll need fireproof party horns!
