Hi I have flowmasters for sale. I have an 05 automatic and I had zero drone and a low rumble, however a little too quite for me so I went with the B&B bullets. Flows are the best bang for the buck otherwise your going to spend over $1k for mufflers then what happens if you don't like the sound? I learned the hard way in that I bought the flows, quite a bit louder than stock, had the low rumble but I wanted to hear the exhaust while I'm driving. Call me crazy[&:]. Anyway first $300 has them plus shipping. Here are some pics and how they sound.http://www.flowmastermufflers.com/pr...7b9fadcc10af50
