glasspacks
Fiberglass-packed resonators
Glasspacks are a type of automotive muffler that uses fiberglass packing around a straight perforated tube rather than internal baffles.
This design allows exhaust gases to flow with less restriction, producing a louder, deeper rumble than standard mufflers.
Popular with car enthusiasts seeking more aggressive exhaust sound: He put glasspacks on his Camaro and now you can hear him coming from three blocks away.
