Whistle tips, often referred to as whistler tips, or whistlers, are modified car exhaust pipes that produce a whistling sound during motor vehicle service, which can often be heard up to a mile away.
The whistle tip is a small metal plate with a central hole, which is welded into the exhaust pipe’s inner end. When exhaust gasses are put under pressure into the exhaust system, they pass through the hole and produce a whistling sound similar to a whistle on a steam locomotive.
