I would reconmend just removing the Mufflers, remove the resonator and place a sinlge Magnaflow Muffler single/dual exahust and put 2 tips at the end. that should eleiminate the Rasp and give you all the sound you want. I am hearing of many people doing this sucessfully and are very happy with the results....I plan to do this eventually....after i pay off my new goodies...hehehe
