A very large muffler usually from 4 - 8 inches in diameter and typically found on most import cars with 4 cylinder engines (eg.. Honda Civic, Mitsubishi Eclipse etc). Many import tuners will use these mufflers in place of the single factory dick pipe exhaust. Commonly named "Fart Pipe" because it makes the 4 cylinder exhaust sound like a very loud farting noise when the engine speeds up. Also see, Coffee Can exhaust, Fart Can.
As I pulled up to the traffic light, a ricer with a Civic pulled up next to me and started revving his engine. His fart pipe exhaust was so loud, it vibrated my car. He obviously thought he was bad ass and was going to race me in my Mustang.

When farting in a sitting position, a fart travels out the butthole, and up the buttcrack, and makes a sound at the top.
