fart blaster
A large muffler that creates a farting noise when added to the exhaust system of a four cylinder car. Generally having a large, chrome tip of about 4" in diameter or larger. These mufflers remove backpressure from the exhaust while also reducing low end torque in most engines, this occasionally makes cars slower than stock off the line and not much faster anywhere else.
