After owning the JGTC PX for 5 months, I finally got to hear what it sounds like from outside of the vehicle. I let a friend do a couple of drive-by's....All I can say is that the sound from inside the car does not even compare to the music it makes outside. It is definitely a sophisticated race-car like sound...My friend commented that the exhaust was worth whatever money I spent on it. My advice to those looking to buy is to hear one "in person" as tastes may vary.
