have you heard the borla s type or atak in person? I just wonder why you go with borla s type and not the atak one. I am still undecide s type or atak because I have not hear it in person. I listen to a bunch of them on youtube, but like most people said, you have to listen in person to really hear the true sound of it.I agree after doing a muffler delete. It was just noise after a certain RPM. I went back to stock and now in gonna wait and pick up a full Borla S Type or Corsa Sport.
