Has anyone bought, installed or listened to any of the Banks exhaust systems? I was looking at the Monster or Stinger systems. I would really like to hear them before purchasing, or at least ask if anyone has listened to them. i dont want an obnoxious sounding exhaust, i want a tuned sound. I am not an overly loud, muddy, sloppy glass pack sounding exhaust. I like the idea of the Stinger system because it addresses the air intake while unrestricting the exhaust. Any comments or sound bites would be greatly appreciated...
