I had the same noise issue, the resonators toned it down A LOT.
I'd go to resonator tips as a last resort, most don't seem to last in the long run.
I should get around to a sound clip one of these days...

i'm in san antonio, for those considering my offer to swap exhausts .... actually, i am planning to upgrade the stereo. already have the head unit with siruis installed, sound deadened the entire interior and ran the speaker wires, amp power wires, and signal cables.
i've had to put the project on the back burner to do some vacationing, buy some furniture and finish off the home theater system, but i'm looking to go forward with a sound quality oriented system, rather than sound pressure level as a winter project.
