When I first installed my Fast Intentions exhaust, I also thought it was too loud. But after a couple hundred miles of break-in time, it actually quieted down a lot. It was a very noticeable change. Now its actually a bit too quiet for me. Go figure. I may end up giving Tony a call to order a different x-pipe (12" or non-res).

Overall, I'd recommend giving your exhaust some time to break-in. It just might settle into a tone that's perfect for you. If after break-in you're still not happy with the sound, you can also try upshifting/downshifting as necessary to get out of the RPM range where droning occurs.
