Default Ford Racing FR500S vs. GTB's vs. Flowmasters

I currently have the Flowmaster American Thunders on my 2007 v6 and it sounds great but also has some annoying drone on the highway. Before them I had the Ford Racing GTB's but they were a little too quiet.

Are the Ford Racing FR500S mufflers a good compromise? I'd like more rumble than the GTB's but less drone than the Flowmasters.
