Remove the 2 mufflers and replace the resonator with one muffler...the main reason rasp hapens is because of the sesoation in the piping to the mufflers...by putting hte mufler closer to the main cat, (eliminating the resonator) it should eliminate most of the rasp....by shortening the exiting pipes you almost elimitaed all together....its what i ahve come to find out experamenting on my freinds contour....but just because it works on his doesn;t mena it will work for you. Bu its something to consider if you want more sound with less rasp
