I just installed the American Thunders on my 05 about a month ago. They sound great. It really deepened the sound of the car. Since I am statioined in Germany I get to open up the car each time I hit the Autobahn. The mufflers are prettly loud cruising at 90+. But having the opportunity to set the cuise at 100 mph is priceless. Plus the 4 inch tips really help the look out back. IMO get the flowmasters. My wife paid about 280 from Jegs and that was the cheapest we could find.
