    sound-dampening-cone-tunes-exhaust-tone.

    This seemingly simple cone-shaped device is deceptive in its appearance. You’d think this sound-dampening component would necessary restrict the free flow of exhaust gases. But its ingenious design incorporates a collection of holes whose total area exceeds the area of an unmodified pipe, resulting in a tuning of the exhaust tone with no increase in back pressure.
