A muffler designed to amplify rather than damp the sound of one's engine; meant to attract the kind of women who fuck axeholes. Often ruins compression and makes a car sound like an angry lawnmower or a pissed-off bumblebee.
I thought having a stereo worth more than your car was a sign of loserdom, but then I saw an eighties Mercedes-Benz with an asshole muffler.
