I deleted the resonator for a girl on a budget. Her I6 resonator must have more solid pieces in it, because it was rattling like crazy. She was worried about the sound, and was pleasently suprised how quiet it still was, and the back end looks tons better without the resonator sticking out in view. We even reused the stock tip. Just do it, if you don't like it, your only out 20-30 bucks.
