fart cannon 

a large "N-1 style" muffler usually attached to import cars. manufacturers usually claim it adds power to cars, however it may adversely affect performance of a car due to lack of necesary backpressure in a cars exhaust. The result of these mufflers is a high decible exhaust that makes the car have less power at low rpms. usually purchased by people who think their car is good when it is actually a pos. Fart canons are a major status symbol in the world of ricers, the louder your 93 horsepower import.... the cooler.

wow look at the fart cannon on that civic.... what a poser
