One of my friends cars has SHM Long Tubes, bassani x pipe and bassani catback with a D1 procharger, but it sounds horrible from outside the car. Like from behind it or as the car is passing by. Is it cause of the long tubes or cause of the forced induction. When he was all motor with frpp shorties and the bassani x and bassani catback, the car sounded great.
