From my experiences with other cars that have a V6, keep the resonators and change out the muffler only. There was another posting with an ANSA muffler. The Magnaflow sounds louder from what I heard on YouTube. The ANSA muffler did sound pretty cool though. I am used to popping into autoparts stores and buying $40-$60 cheap mufflers for V8 muscle cars but in this case you will end up spending atleast $200.
