Mufflers that are packed with fiberglass to muffle the sound. They come in different lengths. The shorter the glasspacks, the louder the car.

A type of exhaust. Features a straight through exhaust tube to provide as much exhaust flow as possible (with holes or baffles in it to direct the exhaust into the packing) that is surrounded by a steel wool or fiberglass packing (sometimes both, varies by manufacturer) to make it relatively quiet considering its a straight through exhaust. Also look up fart can performance exhaust
. Sometimes called cherrybombs because it was a major manufacturer of the exhaust.
"The fart can is the same thing as a glasspack"
"Both the glasspack and fart can exhaust work on the principle of absorption"
"The glasspack enables exhaust to flow better than most chambered exhausts"
