At first we thought the Spinner Exhaust Tip would suck the exhaust out of the engine faster, resulting in more horsepower, but no. It's just another one of those pimp-my-ride thingamajigs that attracts attention to the driver, nonverbally saying things like, "arrest me," or, "I'm an asshole."
The Spinner Exhaust Tip is available in two styles, Flare and Turbine, and it spins just like a pinwheel, propelled by the exhaust stream. If you really floor it, the thing bulges out of the exhaust pipe, telling everyone that you're going fast and making a lot of noise, in case they didn't notice. It's all yours for $44.95.
