Called a "fart can" due to the fact that some sound like a fart. An exhaust that's derived from the glasspack exhaust, it has a straight through exhaust tube to provide as much exhaust flow as possible with a large tip. Usually made from steel and titanium. Mostly found on imported vehicles. It contains a fiberglass or steel wool packing (sometimes both) between the exhaust tube (which has holes or baffles to direct the exhaust into the packing) and the outer shell.
