A huge, annoying, fake exhaust pipe added to the back of piece of s*** cars (Accords, Civics, Eclipses, etc) to make it produce a loud noise as the car accelerates. This does nothing but make the driver seem like an ass, though he doesn't notice because he's blasting his 50 cent CD too loudly. Mostly used by teenagers who think their car is badass. It makes guys who have nice cars (Firebirds, Trans Ams, Camaros, etc) laugh because we have REAL exhaust which is on a REAL car.
Ching Yong: I got this awesome fart pipe on my Civic today.
Me: Well, I have an actual car with actual exhaust, which people don't laugh at as it's going down the street.
