Just installed my Greddy EVO2 system yesterday (took about an hour for my slow, methodical ass) and i have to say that it is my favorite mod to date. it is a very subtle difference over the stock exhaust at lower RPMs, but it has a beautiful, deep sound all across the power band. I drove to work an hour early today, taking every back road i could (radio off) just so i could listen to it. It stinks like ass, though, due to the new internals, but i hear that only lasts a week or two. Question for the EVO2 owners - how much louder does the exhaust get once it is broken in, if at all?
