I went the other way. I originally had the Roush AB with resonators on my car and while it sounded very good, after awhile it would get on my nerves in around town driving. I was also starting to get some drone at around 2,000 rpms.
I finally got the GT500 AB and was happier. Not as loud but loud enough for me. I then bought a set of GT500 OTA pipes with no resonators and now I have the sound I want. Loud when I want it to be and quiet when I don't.
