I would not recommend no mufflers on our cars, they just don't sound very good without some type of muffler. As far as it not hurting your car at all, i don't think it would if you removed it but I think you should look into some mufflers. If you want loud, my Pypes dual violators are pretty loud, or any muffler that is a glass pack would be loud, such as ones by Cherry Bomb or Loud Mouth (dunno what kind of muffler they are but i have heard they are loud as heck). Listen to some exhaust clips online to find a muffler that suits your ears, i think you would be better with one than without.
