Exhaust Whistle - Do you have a friend who thinks they are the coolest cat in town? This is a prank designed to bring them down a peg or two.... it'll make them look really silly!
Once you've cunningly placed the whistle in the exhaust pipe, a (very silly!) squeaky whistle noise will be emitted when the car engine is started, seriously worrying for the driver and seriously funny for you!!!
Spread flanges to fit snugly into any size exhaust pipe. For dual exhaust systems, use two exhaust whistles.
Metal whistle approximately 3.5 cm diameter.
