I just purchased a 08, auto coupe and want to add an aftermarket exhaust,,,but which one? I don't want one that's just about stock sound, but on the other hand I don't want one that makes a classy Vette sound obnoxious or cheap. I have not had the chance to hear them in person and you can only tell so much over the computer. I'm leaning towards a Billy Boat PRT system w/o the x pipe. Any advise would be greatly appreciated prior to spending 1100-1300 dollars! Thanks in advance!
