I'm sure some of you had seen that movie The Wraith. If not, you gotta check it out. Anyway, the car in the movie had an awesome sounding exhaust. Sounded like he had twin turbines. Maybe it was just audio effects. But how can one get that sound instead of the basic sound that most modified 4 cylinder turbo cars have ? If you could get that sound, that alone would turn more heads then anything else.
