Im having the same issues. I have the exact same setup as you and have a rasp that comes on between 4k and 5500 rpm. Its annoying. I was thinking of having the section of the exhaust that goes to 1 pipe cut out and weld in a resonated x-pipe. I've heard that will eliminate the rasp. Magnaflow resonated xpipe is 100 bucks +/- then all you need is some straight peices and a shop that can fab it all up and make it look decent.
