I'll bite... I've got an aftermarket exhaust on my V8 5 series... It actually sounds eerily close to my friends Aston Martin V8 Vantage (stock), and therefore wouldn't classify it was "tasteless". that's pretty cool, and the BMW V8's do sound nice opened up. There are good aftermarket exhausts and bad aftermarket exhausts. I've always liked the sound of Supersprints, never really cared for the loud unbaffled 'American' style systems like Billy Boat Tri-flo or Borla.
