Edit: Mods only make a car perform better, that is if the mods are mechanical, not just looks. I've done many to my own car. Intake, MAF, throttle body, heads, cam, headers, exhaust, muffler, cutout, transmission with shift kit and high stall converter, beefier rear end with quicker gear, stiffer and lower spring and shocks, bigger vented brakes, better pads, shock tower brace, sub frame connectors....
