Every once in awhile you hear a loud *** car driving through the neighborhood. U look and it's a Honda or an integra. How do they do this to an old manual car? I wanna do it to my first car because I can find civics pretty cheap. But what do they do? Aftermarket parts? But I really want the sound they have, I guess u can say they have a "riced" sound. If u got one u can tell me what u did to it
