I'm going to be running longtubes, 3 in offroad h, and 3 inch aftercat on a built kb 2v gt. What is the sound difference between magnaflow mufflers, mac mufflers, flowmaster original 40 series, and bassani? Correct me if I'm wrong, but as far as loudness goes mac>bassani>flowmaster>magnaflow. But how much of a difference is there between the noise level? Is it night and day, or is it just small? I've heard tons of videos but I just cannot tell the noise level. Just need some people who have heard lost of cars. Thanks in advance :beer:
