Turbo Exhaust Whistle Test
Here is a test of the turbo Exhaust whistle on my Ford Focus. The turbo Exhaust whistle is supposed to make a regular car sound like it has a turbocharger on it. The turbo Exhaust whistle fits inside of the Exhaust tip on a car, and it makes a whistling noise when you rev up the engine. You can buy a turbo Exhaust whistle for less than ten dollars on eBay. Watch this video review of the turbo Exhaust whistle to see if you need one.
