I don't see loud cars dying off with muscle cars because I see more obnoxious BMW's along with a few Honda and Infinity with pop and gurgle tunes and open exhaust than Chargers, Mustangs, etc.

Come to south Queens NYC and you'll find plenty of these people. There's a shop around the block from me that builds these noise makers and I get to hear them test drive them up and down the block.
