I went to the muffler shop this weekend and decided to cut out the muffler and leave the resonator. The resultant sound is louder, but not exactly what I was looking for. The exhaust system I have now is stock (minus the muffler) and I am wondering if it would be worth it to upgrade to a 4" or 5" exhaust. Do you guys know of any web sites that have sound files comparing exhausts? I know DD has a couple of clips.
